Abstract
Band assignments of phase‐I PVF2 have been Revised by using additional data obtained by laser Raman spectra of oriented samples. A set of least‐squares refined force constants was obtained which reproduce the experimental data to an average error in frequencies of 1.3 cm−1. In order to determine the effect of electrical polarization on the spectra, a Gaussian distribution of the dipole axis was assumed. The calculation shows that polarizations of less than 60% will not significantly affect the Raman spectra.Keywords
