 Title: THE $\nu_{5}$ BANDS OF $^{10}BH_{3}CO$ AND $^{11}BH_{3}CO$ Creators: Cabana, A.; Lambert, L.; Pepin, Claude; Stone, J. M. R. Issue Date: 1973 Publisher: Ohio State University Abstract: High resolution spectra have been recorded of the $\nu_{5}$ bands of $^{10}BH_{3}CO$ and $^{11}BH_{3}CO$ which occur around $2450 cm^{-1}$ with a resolution of about $0.03 cm^{-1}$. Even under a lower resolution these bands appear to be complicated; these complications arise from the presence of “hot” bands due to $\nu_{5} + \nu_{8} - \nu_{8}$ and also from a Fermi resonance between the $(\nu_{5} = 1)$ and $(\nu_{2} = \nu_{8} = 1)$ levels, both of which have E vibrational symmetry. Many of the K subbands have been analyzed and these results, which will be discussed, have been used not only to obtain good rotational constants but also to further our understanding of these bands.
