From: The effect of temperature and pressure on the crystal structure of piperidine
Thermodynamic parameters of crystalline piperidine. (a) The constant-volume heat capacities of piperidine-h11 (blue) and piperidine-d11 (red). The circles are calculated from experimentally-determined C p values measured for the h11 isotopologue, and the solid blue line is determined from a DFT phonon calculation. The solid red line was obtained from a similar calculation on the d11 system. (b) Variation of the Grüneisen parameter with temperature.
