12.0350.Dorofeeva O.V., 1997None of the statistically calculated values of S(T) known from literature [ Trevissoi C., 1955, Katon J.E., 1959, Aleman H., 1973, Thermodynamics Research Center, 1997] is in full accord with experimental data (see also discussion in [ Chirico R.D., 1989]). Recommended values agree with experimental values within their uncertainties except for temperature range 340-460 K where discrepancies amount to 0.4-0.6 J/mol*K.; GT
