Abstract : The microwave spectrum of methylmonofluorosilane was investigated between 18 and 38 kmc. Several transitions of the isotopic species CH3SiH2F and CH3SiD2F were split into doublets because of coupling internal and over-all rotation; these splittings gave a barrier to internal rotation of 1559 =30 cal/mol. The form of the potential barrier was assumed to be V =1/2 V3(1- cos 3 ), where V3 is the barrier height, and is the angle which gives the relative orientation of the rotor and the framework, V3 may be calculated in 2 ways.
