35.92 | 50. | Dorofeeva O.V., 1986 | Although S(298.15 K) value is 1.6 J/mol*K larger than that obtained from calorimetric data [ Beckett C.W., 1948] and calculated in previous works [ Beckett C.W., 1948, Epstein M.B., 1949, Furuyama S., 1970, Draeger J.A., 1983], it is selected here because of using the most reliable vibrational frequencies in [ Dorofeeva O.V., 1986]. The recommended thermodynamic functions are in good agreement with results of detail force-field calculations [ Lenz T.G., 1989, Lenz T.G., 1990]. Discrepancies with above mentioned calculations amount to 1.6-9.1 and 0.8-6.2 J/mol*K for S(T) and Cp(T), respectively.; GT |
