The microphase separation of n-alkanes with different chain length was investigated by Raman spectroscopy for binary mixture rapidly quenched from the melt. The process was observed as a function of time. The first several minutes after solidificatio

FTIR spectroscopy has been applied to study the thermal stability of magnesium aspartatearginine. An attempt has been made, using theoretically predicted IR spectra, to relate the changes in the experimental spectra with the decomposition process of

In this study, the chemical characterization of airborne bacteria is explored using X-ray photoelectron spectrometry (XPS) and Fourier transform infrared spectroscopy (FTIRS). Samples were taken by using a 6-stage Andersen impactor. Airborne bacteria

Binary solid mixtures of linear n -alkanes were studied using the micro-Raman spectroscopy method. The process of self-organization into mono-component domains was monitored by analysis of shape and shift of spectral bands of alkane samples. One of t

In the FTIR and Raman spectroscopic studies, the phenomena of normal n-alkanes segregation in the binary mixtures of solid-state paraffin at room temperature were examined. Samples, in which one of the ingredients had been deuterated were prepared in

The Raman spectra of Fermi diads of CO2 in gaseous mixtures with nitrogen were measured up to 2790 bars. The perturbed frequencies and the intensity ratio of the bands in resonance have been acquired by fitting the isotropic spectra to the theoretica

The Raman spectra of Fermi diads in gaseous carbon dioxide were measured up to 2155 bars at 50°C. The perturbed frequencies and the intensity ratio of the bands in resonance have been obtained by fitting the isotropic spectra to the theoretical func

The density dependent integrated intensities of the interaction induced (ii) dipole forbidden Raman spectra of the CO2 ν2(πu) mode have been calculated by the use of statistical mechanics based on the quadrupole–induced‐dipole (QID) mechanism.

The interaction induced Raman spectra (IIRS) of 1:0, 1:1, and 1:3 CO2 :N2 solutions have been studied at 50 °C and 75 °C at densities up to 2.5 times the triple point density (90–3010 bars). M0, M2 , and M4 evaluations have been made upon the πu
