Add to ORKGSingle crystal wurtzite ZnO samples have been studied by forward Raman scattering. Spectra were measured at 295 and 75 K using 442 and 488 nm laser lines for excitation below the fundamental absorption edge. Measuring spectra in forward geometry at varied scattering angles allowed achieving small and variable magnitudes of phonon wave vector necessary to observe a polatiton effect. The observed frequencies of the polaritons formed by A1 TO phonons will be compared to the calculated dispersion of phonon polaritons in ZnO
