Abstract
Methyl mercaptan (CH$_3$SH) is a sulfur-containing interstellar molecule, first identified in Sgr B2._x000d_ $footnote{R. A. Linke, M. A. Frerking, and P. Thaddeus,_x000d_ textit{Astrophys. J.} underline{textbf{234}}, L139 (1979).}$ _x000d_ Although the abundance of methyl mercaptan was not too high compared with methanol,_x000d_ the identification of CD$_3$OH towards the IRAS 16293-2422 stimulated our microwave study of CD$_3$SH._x000d_ Deuterium fractionation may be possible for the methyl mercaptan molecule._x000d_ There are many laboratory microwave spectroscopic results on the normal species _x000d_ but the studies on this isotopolog is quite limited. We have observed the spectra of CD$_3$SH in the 12-240 GHz region without gap._x000d_ The pure rotational transitions in the ground and first methyl torsional excited states were assigned. _x000d_ We applied pseudo-PAM Hamiltonian to analyze these transitions._x000d_ We will report the status of the analysis._x000d_
