37.9550.Dorofeeva O.V., 1992p=1 bar. Selected values of Cp(T) coincide with the calorimetric values within 0.3 J/mol*K. The value of -(G-Ho)/T at 298.15 K obtained from absolute intensity measurements in the microwave spectrum [ Curl R.F., 1973] differs by only 0.2 J/mol*K from the value calculated by [ Dorofeeva O.V., 1992, 2]. Discrepancies with the Cp(T) and S(T) values calculated by [ Zurcher R.F., 1955, Zurcher R.F., 1957] amount to 2-10 J/mol*K.; GT
