✦ Synopsis

The high-resolution infrared spectrum of the (v_{5}) fundamental band (antisymmetric SH stretching) of (\mathrm{H}{2} \mathrm{~S}{2}) has been measured with a Fourier transform spectrometer. Approximately (700 \mathrm{H}{2} \mathrm{~S}{2}) transitions of the parallel band were assigned and analyzed by using Watson's (S)-reduced Hamiltonian for asymmetric rotors with all parameters up to sextic centrifugal distortion corrections together with three diagonal octic terms. The full set of rotational constants for the (\nu_{\mathrm{s}}) excited state has been determined for the first time: (A=144) 702.2(11), (B=6977.638(52)), and (C=) (6975.508(52)) in (\mathrm{MHz}). The band origin was determined to be (2558.631662(89) \mathrm{cm}^{-1}). co 1994 Academic Press, Inc.
