Abstract
The molecular crystals naphthalene‐d8 and anthracene‐d10 have been investigated at pressures in the range of ambient to 0.8 GPa and simultaneously at temperatures from room temperature down to 15 K. The accurate frequency measurement of the lattice modes allowed the determination of a small temperature dependence in some of the mode‐Grüneisen parameters. A qualitative comparison of the temperature dependence with theory is made.Keywords
