Özet

We examine here our spectroscopic modification of the first Pippard relation for the paraelectric phase of NaNO2. By establishing a linear variation of the specific heat C-P with the frequency shifts 1/nu 2nu/deltaT for the q[010], q[001] and q[100] modes of NaNO2, we are able to calculate dT/dP values for the paraelectric phase in this crystalline system. Our calculated dT/dP values agree with those given in the literature.
