Abstract:

This thesis presents a joint experimental and theoretical study of vector correlations in the electronically, vibrationally, and rotationally inelastic collisions of simple molecules with rare-gas atoms. In the first instance, empirical and calculated data are presented for rotationally inelastic scattering in the NO(X)+Ar and ND<sub>3</sub>(X̃)+Ar systems at collision energies in the range 405-2210 cm<sup>-1</sup>. These experiments - the first to be conducted on a newly commissioned crossed-molecular beam machine - measured the k-k' correlation, i.e. that between the vectors describing the r

Abstract:

Crossed molecular beam velocity map imaging (VMI) is employed to state-selectively record the NH3 inelastic scattering products from collisions with a series of colliders; atomic Ar, diatomic D2, and the polyatomics CH4, C2H6 and C(CH3)4. The differential cross sections (DCSs) presented for NH3-Ar expand on the existing literature. The angular distribution of the scattering is found to exhibit a dependence on the angular momentum projection quantum number (k) of the NH3 product state in addition to the known dependency on the total angular momentum quantum number (J). It is found that for incr

2008/2009<br>This thesis is aimed to the study of dynamics in binary fluid mixtures by means of inelastic scattering spectroscopies. Nowadays the understanding of these dynamics is still unsatisfactory. In particular, any model is able to adequately describe collective dynamics beyond the hydrodynamic limit. In such a low momentum (k) and frequency () transfer limit, the collective dynamics is characterized by a single (adiabatic) longitudinal acoustic mode accounting for sound propagation. At frequencies above the hydrodynamics ones a transition towards a decoupled dynamic regime is expe

Les calculs théoriques prévoient que la dynamique d’excitation rotationnelle desmolécules CO et O2, induite par collision avec H2, est dominée par des résonancesquantiques aux très basses énergies. Leur mise en évidence expérimentale estrendue difficile par la nécessité d’obtenir des énergies de collision très faibles et unegrande résolution en énergie. Les expériences menées grâce à un montage defaisceaux moléculaires croisés à angle d’intersection variable, nous permettent ainsid’observer le seuil des transitions j = 0  1 de CO à 3,85 cm-1 et Nj = 10  11 de O2à 3,96 cm-1. Ces énergies corr

Abstract:

The majority of structural studies on DNA have been carried out using fibre diffraction, while studies of its dynamics and thermal behaviour have been mainly performed in solution. When the DNA double helix is heated, it exhibits local separation of the two strands that grow in size with temperature and lead to their complete separation. This work has investigated various aspects of this phenomenon. The experiments reported in this thesis were carried out on films of oriented fibres of DNA prepared with the Wet Spinning Apparatus. Thus, sample preparation and characterisation are essential par

Abstract:

The present work is concerned with the mathematical modelling of a bed of granular material in a gravitational field vertically fluidised by a vibrating surface. The particles are in rapid motion, and lose energy by inelastic collisions. The steady state is maintained by a balance of the rate of dissipation of energy in inelastic particle collisions and the rate of transfer of energy due to particle collisions with the vibrating surface. The limit where the energy dissipation due to inelastic collisions is small compared to the mean kinetic energy of the particles is considered. This non-equi

Abstract:

The dynamic shear response and failure of structural elements under transverse impact loads are studied in the present work. The dynamic shear response is one of the important response modes in structural elements under transverse impact loads, which may lead to various shear failures depending on the loading rates and intensities. Transverse shear localization phenomena, which are represented by a shear hinge, have been observed in several structural elements when subjected to transverse dynamic loading and are studied in this thesis. The features of a stationary shear hinge are illustrated u
