Abstract
Raman spectra of the Vs(C=C) stretching mode of phenylacetylene (PA) d issolved in acetonitrile and methylcyclohexane have been recorded at 7 7 K and compared with spectra in the liquid solutions at room temperat ure [Kolodziejski, M.; Waliszewska, G.; Abramczyk, H. J. Phys. Chem. A 1998, 102, 1918]. Substantial narrowing of spectra in frozen matrices at low temperatures leads to revealing of vibrational structure. The results given in this paper are a spectacular example of monitoring st ructural order going from liquid solutions to frozen matrices at low t emperatures by Raman spectroscopy.
