Abstract
The first high-resolution (0.002 cm -1 ) infrared spectra of the reactive molecule thionylimide, HNSO, are reported. The nu 3 (NS stretching) and nu 5 (NSO bending) fundamentals at 1086 and 448 cm -1 , respectively, have been analyzed in detail. The ground state rotational constants have been substantially improved by a simultaneous fitting of previously reported microwave data and a large number of infrared combination differences. The excited vibrational state constants of both type A / B hybrid bands have been obtained from fitting assignments over a wide range of J and K a values. No perturbations were detected in either band.
