8.39450.Dorofeeva O.V., 1986Recommended S(298.15 K) value agrees well with experimental one [ Beckett C.W., 1948], however calculated Cp(T) values are about 5 J/mol*K lower than those obtained from experimental measurements [ Montgomery J.B., 1942]. To fit calculated Cp(T) values to experiment, [ Beckett C.W., 1948] suggested existence of stable half-boat conformation. This suggestion was found to be incorrect later. [ Dorofeeva O.V., 1986] used more reliable data on molecular structure and their S(T) and Cp(T) values are in good agreement with results of detail force-field calculations [ Lenz T.G., 1990].; GT
