Abstract
Low‐resolution infrared studies of silylacetylene and silylacetylene‐d3 have enabled the fundamental vibrational frequencies to be assigned to normal modes of motion. Also, many of the overtone and combination bands have been tentatively asigned. Argon‐matrix spectra at 4.2°K have been helpful in assigning nearly degenerate vibrations, particularly the Si–C stretching motion. Medium‐resolution spectra have enabled approximate values to be obtained for the band origins and Coriolis coupling constants of most of the perpendicular‐type fundamentals.Keywords
