dc.description.abstractThe 2v1 bands for HCC35CI and HCC37CI, the v,+v2+2v4 band for HCC35CI, and the (v1+v4l-v41 hot band for HCC35Ct have been measured between 6370 and 6660 cm-1 using a custom spectrometer based around an external cavity diode laser. Upper and lower state J-values have been assigned to each spectral line measured and confirmed via mathematical modeling of the spectra. A double perturbation was identified and characterized in 2v1 band of HCC37CI and /-type doubling was identified and characterized in the ( v,+v4) 1-v41 hot band of HCC35CI. Rotational and centrifugal distortion coefficients were calculated for all bands, along with additional constants to characterize the perturbed states and the /-type doubling. Modeling using a Voigt line shape was used to subtract the peaks of the HCC35CI main band to allow more complete analysis of the HCC37CI main band and a novel fast-Fourier transform-based method was used for baseline correction. Assignment accuracy of unblended lines for the various bands ranges from 2.5x 104 cm-1 to I.Bx 10-3 cm-1.en_US
