摘要:
Frequency assignments are made, based on the infrared spectra of gaseous di- and triisopropoxyboranes. Correlation with spectra of other alkoxyboranes shows that the BO3 asymmetric stretching frequency is higher than the value previously assigned in the literature. Identification of the C–O stretching frequency in the 1050-1150 cm—1 range supports the interpretation that this region (rather than ca 1300 cm—1) represents the C–O vibration in alcohols.
