Raman Spectra of Hydrocarbons I. 1hyphen;Octene,cis+trans2hyphen;Octene,transminus;3hyphen;Octene,transminus;4hyphen;Octene, 4hyphen;Octyne, and 1hyphen;Octyne

摘要

Raman frequencies, intensities and depolarization factors are reported for 1hyphen;octene,cis+trans2hyphen;octene,transminus;3hyphen;octene,transminus;4hyphen;octene, 4hyphen;octyne, and 1hyphen;octyne. The experimental arrangement is described. The intensities were determined by use of a microhyphen;densitometer. Comparison of the relative intensities obtained in the present investigation for 4hyphen;octyne with the estimated intensities obtained previously indicates that the sohyphen;called ``estimated intensities'' are in reality estimates of densities rather than of intensities. The relative intensities are based upon an arbitrary value of 1000 for the strongest line in the Raman spectrum. A high speed, Hilger Eminus;518 glass spectrograph was used in obtaining some of the spectrograms. With this instrument, a spectrogram of carbon tetrachloride, from which eight lines could be measured, was obtained in one minute.
