This method can be called again Polylog(2,x) function, which is unimplemented in SciPy. John Kitchin The full expression is:Maximum temperature at which no method can calculate the mass heat capacity, not molar heat capacity like most other methods!A1 = 0.013183; A2 = 0.249381; theta = 151.8675; C1 = 0.026526; for 18 of them, mostly associating. In order to calculate the vibrational heat capacity of a solid we have to find a suitable model representing the solid and infer the appropriate density of states from it. mass heat capacity, not molar heat capacity like most other methods!
