The microwave spectrum of normal methyl mercaptan has been studied in the frequency range from 14 to 29kMc/sec. The potential barrier height hindering internal rotation has been determined as 444±10cm^<-1> from the analysis of the lines corresponding to the transitions involving both over-all and internal rotations. The fine structures of J = 1←0, K = 0←0 lines of the various isotopic species have also been analysed and discussed. The molecular structure of methyl mercaptan has been calculated to be d_<SH> = 1.336±0.01A, d_<CS> = 1.819±0.005A, d_<CH> = 1.091±0.01A, ∠CSH = 96°30'±1°, ∠HCH = 109°45'±30° and the angle between CS bond and methyl axis, θ = 2°0'±30'.
