Özet
The Raman frequency shifts (1/v) (partial derivative v/partial derivative T)(T) and (1/v) (partial derivative v/partial derivative P)(T) of the translational mode are correlated to the specific heat C-p and to the thermal expansivity alpha(p), respectively, in D2O ice. Close to the melting point, they correlate linearly, from which the values of the slope dP/dT have been deduced in D2O ice. Our calculated values of dP/dT are in very good agreement with the experimentally obtained value in this crystalline system.
