Where θ E is the Einstein temperature. One linear component, any number of Debye terms, and any number of Einstein terms (along with their respective prefactors) can be manually adjusted in order to identify optimal parameters for modelling heat capacity data. The outputted heat capacity models can be viewed as C p (T ) or C p /T n (T ) plots in linear, log, and log-log scales in order to aid fitting in the high and low temperature regions.
