9.23050.Dorofeeva O.V., 1986S(T) values calculated by [ Stull D.R., 1969] are in good agreement with those selected here; however, the discrepancy in Cp(298.15 K) amounts to 6.2 J/mol*K. S(T) values calculated by molecular mechanics method [ Chang S., 1970] are about 13 J/mol*K less than recommended ones; discrepancies in Cp(T) values amount to 1-2 J/mol*K.; GT
