Abstract
The results of the structure features and intermolecular interaction investigations in long-chain aliphatic compounds (LCAC) by JR spectroscopy (experiment, the theory), differential thermal analysis, polarizing microscopy, and X-ray methods have been generalized. The objects for the researches have been the carboxylic acids derivatives (alkyl- and alkyloxybenzoic, alkylcyclohexanecarboxylic and their completely or partially fluoroalkyl substituted), 4-n-alkyl-4'- cyanobiphenyls, 4-n-alkiloxy-4' -cyanobiphenyls n-n' -butyloxybenzoate of cholesterol. The results of investigations have been proved by the data of the infra-red spectrum LCAC modeling taking into consideration conformational mobility of molecules and intermolecular specific interaction (H-bond). Both factors become apparent in JR spectra and determine LCAC structure features. It is established, that the conformational mobility of molecules.
