Paper Abstract

Raman spectra of hydrocarbon and fluorocarbin zigzag structure molecules are studied. The investigations have been fulfilled for following substances: CnH2n+2 (n equals 6, 7, 10), CnH2nO2 (n equals 4, 5, 8, 10, 11, 13, 15, 18), CnF2n+1Br(n equals 6, 7, 8, 10, 14), for similar structures: H(CF2)10H, H(CF2)10CONH2, F(CF2)5CO2K and commercial products. The frequency shifts of some modes, corresponding to acoustical and optical vibrations, have been observed. The theory, explaining Raman modes frequency dependence on the length of zigzag molecule, is developed. The presence of characteristic isooctane line in Raman spectra of benzines is established. Molecular structure modification of sun- flower-seed oil as a result of technological preparation process has been observed. The obtained results allow detecting zigzag fluorocarbon and hydrocarbon molecules in media and estimating its length with the help of Raman scattering spectroscopy.
