Abstract

The electric dipole moment of CF3CH2F (HFC-134a) has been determined with a good accuracy by observing the second order ΔMJ = 0 Stark spectrum of the J = 50,5 ← 41,4 rotational transition. In addition, the equilibrium geometry and the dipole moment have been evaluated using highly accurate ab initio methods. By comparing the experimental [μa = 0.4909(14) D and μb = 2.0254(39) D] and theoretical [μa = 0.35(1) D and μb = 2.02(1) D] dipole moment components, a very good agreement has been found.
