Abstract

Methanethiol, CH3SH, has been found in the warm and dense parts of high as well as low mass star-forming regions.a The molecule is also of fundamental interest because of the large amplitude internal rotation of the CH3 group whose effects are somewhat less pronounced than in its lighter homolog CH3OH. In the course of our ongoing study of CH32 3 SH,b we have recorded new spectra which currently cover 49−510 GHz.c These spectra, as well as existing ones covering part of the 1.1−1.5 THz region,d were inspected for lines of CH34 3 SH. We made extensive assignments of ∆K = 0 transitions in vt = 0 to 2. Numerous assignments of ∆K = ±1 transitions were made in vt = 0 and to a lesser extent in the two higher torsional states. We will present results of modeling these data with the RAM36 program and of searches for this isotopolog in our 3 mm ALMA data of Sagittarius B2(N).
