Rotationally resolved, laser-induced fluorescence spectra of $Rg\cdot SH$ complexes have been recorded for the first time. These complexes were produced by the photolysis of a mixture of 1% $H2S$ in He with a small amount of the appropriate inert gas. The molecule was jet cooled and probed with a pulse amplified cw ring dye laser with a resolution of 300MHz in the UV. We observe both fine and hyperfine structure in $Ar\cdot SH$ analogous to $Ar\cdot SH$. We have also confirmed that previously unidentified bands of $Ar\cdot SH1$ are in fact combination bands of both the van der Waals stretch and bend. Spectra of all previously observed pure van der Waals stretch bands of $Ar\cdot SH$ have now been recorded and we will discuss the analysis of these bands. Presently work is also in progress on the $Ar\cdot SH$ and the $Kr\cdot SH$ complexes.
