With the recent development of zero kinetic energy threshold photoelectron spectroscopy (ZEKE-PES) it is now possible to take advantage of the high resolution capabilities of laser radiation and measure the rotational distributions of many small cations produced via photoionization. We have used threshold photoelectron spectroscopy in conjunction with a VUV laser source to probe the rotational distributions of several molecular cations following one- photon VUV photoionization. Spectra are obtained by the delayed, pulsed field ionization (PFI) method which is a variant of the ZEKE- PES technique. In this paper, we report on the rotationally-resolved threshold photoelectron spectra of the non-linear triatomic H{sub 2}S. These measurements are an extension of our earlier study on H{sub 2}O which provided the first look at the symmetry properties of allowed rotational transitions in the photoionization of non-linear molecules.
