Infrared Spectra of Alkyldiboranes. V. Tri‐ and Tetramethyl‐ and Ethyldiboranes

Abstract

Frequency assignments are reported for the infrared spectra of tri‐ and tetramethyl‐ and ethyldiboranes, together with some of their boron‐deuterated and B¹⁰ isotopic derivatives. Additionally, a Raman spectrum of tetramethyldiborane from sources in the literature is analyzed. In assigning some of the B–C stretching frequencies, use is made of the recently formulated Average Rule.
