Experimental Resultsthe vibrational spectrum of this hydrocarbon is of great significance for understanding the structure of the molecules in other six-membered naphthenes. In addition to this, the cyclohexane molecule has a high symmetry; vibrational calculations have already been carried out for it , so that i

Methods of Obtaining and Analyzing Low-Frequency Raman Spectraor studying Raman spectra, is unsuitable for recording low frequencies. This is because of the very strong continuous background, which lies close to the exciting line and falls off gradually on moving away from it. In the present investigation we used the photographic method of recording spectra; t

Appearance of the Rotional Oscillations of Methyl Groups in Low-Frequency Raman Spectraonstituted a good type of sample. We see, for example, from the structural formula of methylcyclohexane.that, apart from the rotational oscillations of the CH. group, only deformation oscillations can appear in the spectrum. We can hardly expect substantial intermolecular interactions in these subst

Measuring Methodure, S. is the entrance slit of the polarization system (in particular cases the light source may appear in place of slit S.). The slit S. is placed at the focus of the objective O.. In all forms of the system, even in the shortwave part of the spectrum, we used mirror optics. In this case, O. and O
