Paper Abstract

Activity of molecules in biological system depends on their conformation. NMR spectroscopy study of molecule conformations requires replacement of atoms by their isotopes. X-ray diffraction study is limited by an opportunity of reception of crystal samples with perfect structure. Biological systems, for example the cell membranes, are liquid crystal systems hence have imperfect crystal structure. Molecule conformations of substances with such structure can be investigated by use of more long-wave radiation. In this case the imperfection of structure will be less essential. In this paper we show the efficiency of joint application of experimental molecular vibrational IR spectroscopy and computer simulation of spectra, with correction of force constants and electrooptical data for phase state change, in study of conformations of liquid crystal molecules.
