Abstract: Raman scattering from polaritons of mixed B2-E symmetry has been observed in potassium dihydrogen phosphate at ambient temperatures. An extraordinary polariton branch has been measured at wave-number shifts from 940 cm-1 at 0.3°of arc internal scattering angle to 1080 cm-1 at 2.0°internal scattering angle. A formula is derived that relates scattering angle and propogation angle in anisotropic, uniaxial crystals. Experimentally measured frequencies are in good accord with theoretical calculations. © 1979 The American Physical Society.
