AB  - A new empirical equation for liquid heat capacity calculation, as a function of temperature and pressure is recommended. This four-parameter equation was tested and compared to the four-parameter equation developed by Guseinov et al. (1988), five-parameter equation developed by Garg et al. (1993) and nine-parameter equation developed by Nakagawa et al. (1993), using 73 sets with 4395 literature experimental heat capacity data for 46 chemical compounds. The obtained results indicate that the proposed four-parameter equation gives in many cases better results than the tested four- and five-parameter equations and in few cases even better than the nine-parameter equation.

AB  - The infrared spectra have been recorded for thirteen 3-substituted-5,5-dimethylhydantoins in the region of fundamental C=O stretching vibrations in dichloromethane. The frequencies of symmetric and asymmetric C=O stretching vibrations are correlated with Taft's sigma* substituent constants. When the electron-releasing substituents are in position-3 in the hydantoin ring the stretching frequency increases with the increase in the electronegativity. However, the effect of electron-withdrawing substituents appears to be quite opposite, i.e. the carbonyl stretching vibrations are decreased. The correlations with extended Hammett equation Q(x) = alpha sigma(1) + beta sigma(R) + h and with Swain-Lupton equation p(ij) = fF + rR + h give the results which according to Jaffe can be considered as poor. The correlation obtained from Hammett sigma(p) constants furnish satisfacory results except the substituents with a wide range of polarity. The mechanism of the transmission of substituent effects in hydantoin systems is discussed considering the results of above mentioned observations.
