ABSTRACT. The vapour pressure and sublimation enthalpy of HLCP-purified C84 have been determined by Knudsen cell mass spectrometry in the temperature range 658-980 K; the temperature-pressure equation is ln(p/Pa)=(- 24337+-539)/T(K) + (25.15+-0.64), and the mean sublimation enthalpy at 853 K is 202+-4 kJ*mol-1
