THE VIBRATIONAL SPECTRA OF ISOBUTANE AND ISOBUTANE-d1

Abstract

The Raman spectra of liquid (CH3)3CH and (CH3)3CD 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 C3ν symmetry and their spectra correlated.
