Abstract:
Our fundamental knowledge of interstellar grain composition has grown substantially during the past two decades thanks to significant advances in two areas: astronomical infrared spectroscopy and laboratory astrophysics. The opening of the mid-infrared, the spectral range from 4000-400 cm−1 (2.5-25 μm), to spectroscopic study has been critical to this progress because spectroscopy in this region reveals more about a material's molecular composition and structure than any other physical property.

Abstract Dispersion spectroscopy based on frequency measurement of the high finesse optical cavity mode shifts induced by the presence of a gas medium with absorption resonances is an attractive alternative to standard absorptive spectroscopy. The main advantage of such pure frequency-based dispersive spectroscopy technique is the unique combination of sensitivity and accuracy. High sensitivity is ensured by high finesse optical cavities providing extremely long effective optical paths. On the other hand, high accuracy is provided by frequency measurement cavity mode shift.

Abstract:
In recent years, a large number of linear and nonlinear laser-based diagnostic techniques for detection of pollutions in different environments have been developed. Applications of laser spectroscopy constitute a vast field, which is difficult to cover comprehensively in a review. Due to that here are presented only a few spectroscopic methods, chosen to illustrate the power of applied laser spectroscopy in environmental pollution investigation. The paper also gives a brief presentation of main laser spectroscopy methods.

Abstract:
Non-invasive optical spectroscopy consistently delineates compositional and physiologic properties of breast tissues serving as a premammography risk marker for cancer or yielding a high assurance of no such risk. We believe this new non-imaging approach depends on biochemistry of tissues rather than on the macroscopic physical properties involved with most breast imaging modalities. After establishing the procedure as inexpensive, physician independent, simple, requiring only a few minutes and appealing to women, it was carried out in two institutions on 1739 women referred for routine mammog

Abstract:
The principle and application of ultrafast optical Kerr effect (OKE) spectroscopy have been reviewed. This spectroscopy is shown to be very useful to investigate low frequency modes in disordered materials and the obtained data are directly comparable with frequency-domain light scattering spectroscopy. Experimental study to show the consistency between the time- and frequency-domain spectroscopy has been performed for liquid nitrobenzene and the excellent agreement is attained over three orders of magnitude in frequency range. It is also shown that the result obtained by the OKE measurement i

Abstract:
Raman spectroscopy, one of the most widely used optical spectroscopic technique can provide molecular information about pharmaceutical drugs. This particular spectroscopic technique has proven its potential over the others by overcoming the barriers faced in traditional approaches and by providing unique benefit of molecular characterization in near real time. In this spectroscopy method, incident light interacts with the molecule inelastically and the scattered light has specific vibration modes of molecules in form of sharper Raman peaks. The technique thus can identify the molecular structu

Abstract:
Many of the historical objects that form our cultural heritage are made of wood. Wooden artefacts, wood painted panels and historic furniture represent a significant part of our cultural heritage. Their preservation over time is a challenging task, and insect infestation still represents a primary cause of loss of cultural heritage artifacts. For this reason in this research, wood pigments that are important in the conservation of historical wooden objects are described. The characterization of very stable pigments from a cultural heritage building named by SAGHATALAR which is located in Mazan
