gas104.cal/mol*KN/AMarcus Y., 1986This value calculated from published spectroscopic and structural data is in close agreement with estimations by a method of increments (440-451 J/mol*K [85MAR/LOE, Dorofeeva O.V., 1997]). Value obtained from calorimetric data (508.5 J/mol*K [85MAR/LOE]) authors do not regard as reliable. Results of statistical thermodynamics calculation [ Puranik P.G., 1962] are likely to be erroneous (S(300 K)=319 J/mol*K).; GT
