✦ Synopsis

The first high-resolution (0.002 cm 01 ) infrared spectra of the reactive molecule thionylimide, HNSO, are reported. The n 3 (NS stretching) and n 5 (NSO bending) fundamentals at 1086 and 448 cm 01 , 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.
