✦ Synopsis

nitrogen q dichloromethane g at standard atmospheric pressure pЊ over the temperature Ž . range 323.2 to 423.2 K. The measurements were analysed using pair potential parameters for nitrogen, assuming suitable combining rules for the calculation of cross-terms, and finding parameters of the Stockmayer potential for dichloromethane which fitted the excess enthalpy measurements. These parameters are rk s 722 K, s 0.318 nm, and t* s 0.289. Second Ž . virial coefficients calculated from these parameters are in accord with those from p, V, T experiments.
