Spectroscopic studies of Lewis acid-base complexes--I : Vibrational spectra and assignments for trimethylymine complexes of boron halides

Infrared and Raman spectra of 1:1 complexes of trimethylamine with boron trifluoride, boron trichloride and boron tribromide have been obtained in the solid state. Samples studied included those isotopically enriched in B10 as well as those containing the natural isotopic ratio of B11 to B10. On the basis of isotopic shifts and trends of frequencies within the series, vibrational assignments of the observed frequencies are proposed.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/32098/1/0000148.pd
