The Raman Spectrum of Tetramethylmethane

Abstract

Raman spectra of tetramethylmethane, the mono chloro derivative of tetramethylmethane and n‐amyl chloride, have been obtained with a spectrograph which gave a dispersion of 14A/mm at λ4500. Filters were employed which permitted the observation of the weaker lines. The rather simple arrangement of very intense quartz water‐cooled vacuum mercury arcs is described. The results for tetramethylmethane confirm the predictions of the theory of the vibration spectrum of the hydrocarbons which was developed by Kohlrausch and Barnes.
