摘要：

Based on theoretical considerations, an i.r.-technique is presented which allows the mean CF2 dipole orientation to be determined in uniaxially drawn poly(vinylidene fluoride) (PVDF) in dependence on an external electric field applied to the sample during spectra registration. The method includes measurements at different angles of incidence. Information about dipole orientation in trans-sequences of different lengths or in crystallites and in non-crystalline regions may, in principle, be obtained.
