Abstract

The elastic stiffness constants for the calculation of the thermal diffuse scattering correction of X-ray reflexions should be the isothermal ones. However, adiabatic ones are mostly used. It is shown that, despite a relatively large difference between both types of elastic stiffness constants for pyrazine, the resulting thermal diffuse scattering correction is hardly affected.
