Infrared Spectra of Alkyldiboranes. I. Monomethyldiboranes

Abstract
The infrared spectra of five isotopic derivatives of monomethyldiborane (CH3B210H5, CH3B2H5, CH3B2D5, CD3B2H5, and CD3B2D5) are analyzed and frequency assignments are made through correlation with trimethylborane and terminally substituted B2H5D and B2D5H.
