Abstract:

This study investigates the photophysical properties of Nile Blue 690 (NB-690) dye using spectroscopic techniques. Absorption and fluorescence spectroscopy were used to analyze NB-690, revealing pronounced bathochromic shifts in both absorption and fluorescence spectra, indicative of the π → π* transition. The study focuses on estimating ground- and excited-state dipole moments of NB-690 through solvatochromic shifts in absorption and fluorescence spectra. Various computational methods, including the Bilot-Kawski approach for ground state dipole moment computation, and the Reichardt correlatio

Abstract:

The aggregation ability and exciton dynamics of dyes are largely affected by properties of the dye monomers. To facilitate aggregation and improve excitonic function, dyes can be engineered with substituents to exhibit optimal key properties, such as hydrophobicity, static dipole moment differences, and transition dipole moments. To determine how electron donating (D) and electron withdrawing (W) substituents impact the solvation, static dipole moments, and transition dipole moments of the pentamethine indocyanine dye Cy5, density functional theory (DFT) and time-dependent (TD-) DFT calculatio

Abstract:

The observed value of the magnetic dipole moment of the electron is much larger than that allowed by electromagnetic theory. In particular, Maxwell's equations, together with the known upper bound on the size of the electron predict a magnetic moment much smaller than the observed one, even if the particle is rotating at the speed of light! In gravitation with an asymmetric connection, the intrinsic spin of an elementary particle gives rise to torsion. It is shown here that this source, spin, can also give rise to the observed magnetic dipole moment of the electron, and do so with no moving pa

It is shown that models containing both SU(2) singlet fermions and a singlet Higgs have interesting effects on the electric dipole moment of the electron. Unlike the neutron dipole moment, there is no QCD suppression in this case. It is thus possible to find useful constraints on models that include both these kinds of singlets.

Abstract:

Two studies of aspects of modelling dipole moment functions of XH bonds in small molecules for use in calculating overtone intensities have been undertaken. The first study deals with the fitting of ab initio calculations of the dipole moment at discrete points to a functional form. The two methods that are compared are the use of least-squares regression and the use of interpolating polynomials. The interpolating polynomial method is deemed superior due to its greater efficiency in terms of the number of points necessary to obtain reasonable results.

The imbalance of matter and antimatter in our Universe provides compelling motivation to search for undiscovered particles that violate charge-parity symmetry.

Our result is consistent with zero and improves on the previous best upper bound by a fact

Discovering an electron electric dipole moment (e-EDM) would uncover new physics requiring an extension of the Standard Model. e-EDMs, large enough to be discovered by new experiments are now common predictions in extensions of the Standard Model, including extensions that describe baryogenesis, dark matter, and neutrino mass. A cesium slow-atom e-EDM experiment (which is similar to an atomic clock) can improve the sensitivity to the e-EDM. And, as with an atomic clock, it could be more sensitive in microgravity than on Earth. As a first step an Earth-based demonstration Cs fountain e-EDM expe

We study the contribution of the doubly charged higgsino to the electric dipole moment of the electron in a left–right extension of the standard supersymmetric model. The CP violation comes from the trilinear scalar interaction terms in the selectron mixing matrix.

The stabilities of the parent compounds follow the order 5-NO2 ~ 4-NO2 > 2-NO2. In solution 4-nitro is more stable than 5-nitro; the calculations suggest that this is a solvation effect, since the 4-nitro isomer has a considerably higher dipole moment.

Abstract:

This study investigates the interactions between electron carriers that facilitate electron transfer. Specifically, it examines Flavodoxin (Fld), which replaces Ferredoxin (Fd) as the electron carrier from Photosystem I (PSI) to Ferredoxin-NADP⁺ reductase (FNR) in <em>Anabaena</em> cyanobacteria under iron-deficient conditions. The researchers determined the dipole moment of Fld and demonstrated that the negative end of its strong dipole is oriented toward the flavin ring, influencing its interactions with the positively charged surfaces of PSI and FNR. By introducing single and multiple charg

Abstract:

The influence of halides on the electronic structures of polyoxotitanate cages is explored in this experimental and theoretical study. Dipole moment, crystal-field splitting, Nephelauxetic influence of the halide and electron–electron repulsion all play a role.

Abstract:

Abstract The effect of substituents R (R=N(CH3)2, OCH3, CH3, H, Cl, Br, CN) on the polarity of trans-styryl-methyl-sulfones in the first excited singlet state is investigated. Linear relations are found between the dipole moment in the excited state, μe, and the Hammett constant, σp+ , and also between μe and the dipole moment in the ground state, μg. On increasing the electron-donor power of R, μe grows faster than μg.

Abstract:

Levofloxacin (LVF) and norfloxacin (NRF) are a group of fluoroquinolone antibiotics, broad spectrum used to treat various infections caused by many bacterial species. The drugs contain functional groups which control the type and degree of interaction with different solvents. In this research, the ground and excited state dipole moments of LVF and NRF drugs were estimated using solvatochromic effects and computational work. The dipole moments were estimated from absorption and emission spectra in polar and nonpolar solvents using Bakhshiev’s, Kawski–Chamma–Viallet, Lippert–Mataga, and Reichard

Abstract:

The P , T -odd Faraday effect (i.e., rotation of the polarization plane of light propagating through a medium in presence of the external electric field due to P , T symmetry violating interactions) is considered for several atomic species: Ra, Pb, Tl, Hg, Cs, and Xe. Corresponding theoretical simulation of P , T -odd Faraday experiment, with already achieved intracavity absorption spectroscopy characteristics and parameters, is performed. The results show that the magnetic dipole transitions in the Tl and Pb atoms as well as the electric dipole transitions in the Ra, Hg and Cs atoms are favor

Abstract:

Ab initio calculations on a series of trisubstituted amines, phosphines, and arsines are presented at the MP2/6-311G(d,p) level. Specifically, the species studied are XH3, XF3, and X(Me)3, where X = N, P, or As. The influence of the substituents on the proton affinity is analyzed in terms of the charge distribution, its topology, some one-electron properties (dipole moments, electric field gradients), and dipole polarizabilities. An atoms-in-molecules. decomposition of the charge distribution, energetics, and polarizabilities also proves informative. There seems to be no straightforward way of

In this research paper, thin films of polyethersulfone reinforced with different concentrations of the zinc-nickel ferrite nanoparticles [ZnNiFe] using the spin coating technique is presented and briefly discussed. The polymer chosen was polyethersulfone. Optical characterization of the test samples was carried out using different spectroscopic techniques at room temperature [25°C]. The structural properties, texture, and morphological characteristics of the as-prepared thin films were studied using the techniques of Fourier transform infrared spectroscopy [FTIR], X-ray diffraction [XRD] spect
