The Ground State Microwave Spectrum of 2-Fluoropropane

Abstract

We determined the internal rotation barrier V 3 = 3.285 kcal/mol (13.74 kJ/mol) and the moment of inertia Ix = 3.184 amuÄ2 of the methyl groups from the ground state microwave spectrum of 2-fluoropropane. Additionally the rotational constants, the quartic and some sextic centrifugal distortion constants are reported. The analysis of the Stark effect leads to the dipole moment 1.958 D.
