This is the final report of a series of papers from this laboratory on the internal motion and the structure of methyl amine. Most of the observed lines including J = 1←0, K = 0←0 lines were analyzed in the frequency range between 4 and 50kMc/sec. The barrier height of internal rotation has been determined to be 691.1cm^<-1> as well as the molecular structure, d_<CN> = 1.474A, ∠HNC = 112°10', ∠HNH = 105°50', ∠HCH = 109°30' and the angle between CN and methyl axis = 3°30' on the assumption that d_<CN> = 1.093A and d_<NH> = 1.014A. These results were compared with the barrier height and the structure of other CH_3 MH_1 type molecules, methyl alcohol and methyl mercaptan. The inversion doubling of the observed lines was also analyzed satisfactorily. The quadrupole coupling constant of N^<14> along the charge symmetry axis has been obtained as -3.6±0.3Mc/sec, with the direction of the axis, 90°±8, from the methyl axis.
