THE HIGH RESOLUTION VIBRATION-ROTATION BANDS $\nu_{2}$ OF $^{10} B$ AND $^{11}BD_{3}$C0 AND THE STRUCTURE OF BORINE CARBONYL

Author Institution: Department de Chimie, Universit\'{e} de SherbrookeThe high resolution infrared vibration-rotation spectra of both $^{10}BD_{3}$CO and $^{11}BD_{3}$CO have been obtained in the region of $2170 cm^{-1}$. The $v_{2}$and $\nu_{2}$ + $\nu_{8}$ - $\nu_{8}$ bands of both Isotopic molecules were analysed and band constants calculated. The two rotational constants $B_{0}$ obtained from this study may be used with the $B_{0}$ previously obtained for the $^{10}BH_{3}$CQ and $^{11}BH_{3}$CO molecules to calculate the four structural parameters of borine carbonyl. It will be shown that, because of the high degree of correlation between two molecular parameters, there exists a large uncertainty in two of the four molecular parameters
