dc.description.abstractThis study gives our relations between the specific heat C P and the Raman frequency shifts (1/v)(partial derivative v/partial derivative T)(p) for the lattice modes of v(5) (144 cm(-1)) and v(5) (174 cm(-1)), when the mode Gruneisen parameter gamma(p) depends on the temperature near. the lambda-transition in NH4Cl (T-lambda = 242.5 K, P = 0). From our linear relations between C-p and (1/v)(partial derivative v/partial derivative T)(p), we deduce the values of the slope (dP/dT)(lambda) for both lattice modes in this crystal. Our (dP/dT)(lambda) values remain almost the same as those which we calculate when gamma(p) is taken as a constant close to the lambda-transition in NH4Cl. Our calculated values for (dP/dT)(lambda) are reasonable in compared to the experimental values.en_US
