An investigation has been made to determine if TROUTON-PICTET's rule, valid for phase transitions, can be extended to dissociation processes for diatomic molecules. Comparing the entropy increase from the non-dissociated to dissociated states, a common law exists for all diatomic molecules examined.If the procedure is performed at a certain "fix-point", the maximum of the specific heats, an average value of approximately 30 cal/Mol · K for entropy gain results. Since the TROUTON-PICTET rule is
