Low-temperature heat capacity of benzene crystalline derivatives
The primary objective of this proposal is to generate new experimental data on the low-temperature heat capacity of specially selected chloromethyl substituted benzene crystals, covering a temperature range from 2 to 300 K. Additionally, the study aims to investigate order-disorder phenomena in aromatic compounds composed of planar molecules with controlled substitution outside the methyl group by chlorine atoms. It is anticipated that this substitution will significantly impact both the position and amplitude of the calorimetric boson peak at temperatures below 10 K.
