 Title: HIGH RESOLUTION SPECTROSCOPY OF THE $a^{3}\Pi_{r}-X^{1}\Sigma'$ TRANSITION OF BCl Creators: Mahoney, K. I.; Brett, R. J.; Mathews, C. W. Issue Date: 1994 Abstract: The $a^{3}\Pi_{r}-X^{1}\Sigma^{-}$ transition of BCl has been recorded at $0.02 cm^{-1}$ resolution using a Bruker IFS 120 HR Fourier Transform spectrometer The $\Delta\nu=0$ bands up to $\nu^{\prime}=4$ and $\Delta\nu=-1$ bands up to $\nu=1$ were observed, and 693 fines were assigned. The increased dynamic range of intensities for the fourier transform spectrometer over photographic recordings has allowed for the first rotational analysis of all four isotopomers of BCI. The most intense band, the 0-0 near $20 200 cm^{-1}$, has been analyzed for $^{11}B^{35}Cl, ^{11}B^{32}Cl ^{10}B^{35}Cl,$ and $^{10}B^{32}Cl4$. The standar deviation of these fittings was about $0.015 cm^{-1}$, and the constants are in agreement with previous reports $^{1,2}$ The other bands are currently be analyzed.
