THE VIBRATIONAL SPECTRA OF ISOBUTANE AND ISOBUTANE- d 1

Abstract

The Raman spectra of liquid (CH 3 ) 3 CH and (CH 3 ) 3 CD were obtained photo-electrically and intensities and depolarization ratios measured. The infrared spectra of the corresponding gases were obtained from 3 to 35 μ. A vibrational assignment consistent with depolarization ratios and band contours has been made for the molecules on the basis of C 3ν symmetry and their spectra correlated.
