8.98250.Dorofeeva O.V., 1986Recommended values are in good agreement with those calculated by [ Kilpatrick J.E., 1947, McCullough J.P., 1959] at low temperatures. The discrepancies increase at higher temperatures and amount to 1.8 J/mol*K for S(1500 K) and 2.1 J/mol*K for Cp(1500 K) obtained by [ McCullough J.P., 1959]. Calculation [ Sundaram S., 1963] seems to be incorrect because discrepancies with these data reach 23 and 7 J/mol*K for S(T) and Cp(T), respectively.; GT
