%X The far infrared reflection spectra of n-GaAs1-xPx with x= 0.328 and x = 0.40 are investigated in the frequency range of 40-700 cm-1 and the temperature range of 4.2-300 K. The important physical parameters describing the optical phonons, plasmon and LO phononplasmon coupling mode of the material and infrared optical constants are obtained by the multioscilla-tor fitting and K-K relation calculation. A model of two conduction band valley with a donor level below and associated with X minimum is presented to explain the behavior of the dependence of plasmon frequency on temperature and the variation of the three coupling modes with temperature.
