Abstract
Rotational level structure of 12 vibrational states of CH2DI with energies in the 1000-1800 cmâ1 region has been retrieved from high resolution (0.001-0.003 cmâ1) FTIR spectra. Eleven vibrational states, namely, 21, 3161(Aâ²), 51(Aâ²â²), 3161(Aâ²â²), 62(Aâ²), 51(Aâ²), 61(Aâ²) 61(Aâ²â²), 2131, 62(Aâ²â²), 3261(Aâ²) and 3151(Aâ²â²) have been found to interact. A total of 27 919 transitions belonging to diverse fundamental, combination and hot bands were assigned and used in the combined nonlinear root mean square fit to give the band centers, rotational, centrifugal distortion and coupling parameters of the states under investigation. The RMS deviation of the fit has been demonstrated to be 0.000218 cmâ1. The number of the coupling parameters required to reproduce the observed spectra with the experimental uncertainty appeared to be 46.
