Calculation of diamond heat capacity by its spectroscopic and elastic characteristics

We calculate the heat capacity of diamond based on the inelastic neutron scattering data and elastic characteristics of the crystal at the temperature range of the diamond phase existence. We analyze the diamond phonon spectrum and reasons for heat capacity anomaly at low temperatures (under 100 K). We show that due to thermal expansion at temperatures under 300 K, the input into heat capacity has values not exceeding the measurement error in current adiabatic methods
