9.31650.Thermodynamics Research Center, 1997p=1 bar. Thermodynamic functions calculated by [ Compton D.A.C., 1977] are larger than recommended ones up to 1.5 and 2.0 J/mol*K for Cp(T) and S(T), respectively. [ Durig J.R., 1976] have calculated thermodynamic functions for s-trans conformer. Their Cp(T) and S(T) values are lower than those of [ Thermodynamics Research Center, 1997] by 1-4 J/mol*K.
