Abstract

The potential function hindering internal rotation in 3-fluoropropene has been determined from far infrared and microwave spectroscopic data, and is described by the first six Fourier cosine coefficients. The model used for the development of the Hamiltonian is that of a pure torsional mode in an otherwise rigid molecule. The torsional equation is expressed in the form $H_{T}= p^{2}F(\alpha) +F(\alpha)+ p^{2}+2pF(\alpha)p+V(\alpha)$ where $\alpha$ is the torsional angle and $F(\alpha)$ is proportional to the inverse effective reduced moment of inertia for the torsional mode.
