38.3150.Thermodynamics Research Center, 1997p=1 bar. Selected entropies and heat capacities agree within 2 J/mol*K with statistical values calculated by [ Shvaro O.V., 1987] except for S(1000 K) which value is about 6 J/mol*K lower than that of [ Thermodynamics Research Center, 1997]. Discrepancies with statistical calculation of [ Andreevskii D.N., 1976] amount to 4-12 J/mol*K for S(T) and 3-8 J/mol*K for Cp(T).; GT
