Because a search of the current literature failed to yield complete vibrational IR data for CH3SiH3 and CH3SiD3, the IR spectra of these molecules are reported for the region between 450 and 10,000 linescm. The fundamental frequencies are assigned to normal modes of action, and assignments are given to many of the overtone and combination bands. The high-resolution IR spectra of 6 bands of CH3SiH3 and of 2 bands of CH3SiD3 in the 2000 to 5000-linescm region are reported. A HIGH RESOLUTION INFRARED STUDY OF DISILANE IN THE REGION 2000-5000 cm-1, by R. E. Wilde. 31 Aug 61, 18p. incl. illus. tables. 11 refs. The present work reports the analysis of an IR band at 2169.42 cm-1 which corresponds to the fundamental Si-H stretching motion, and the analysis of a combination band at 4256.36 cm-1. Both bands are perpendicular type bands.
