The Raman polarization spectra of a single crystal of natural phillipsite in the wave number region 50–4000 cm −1 were measured at laboratory temperature. The vibrations observed in analysis of the measured polarization spectra can basically be divided into 4 groups: a) H 2 O‐vibrations, b) Internal vibrations of bonds within the (Al, Si)O 4 tetrahedra, c) External vibrations between tetrahedra, d) Optical translational modes of the crystal lattice.
