Abstract : The heats associated with the reaction of N2F2 with NH3 were observed for two mixtures containing the trans and the active isomers of N2F2 in different proportions. From the observed heats of reaction the heats of formation were determined to be 1/19.4 ! 1.3 and 1/16.4 ! 1. kcal mol for the trans and theACTIVE ISOMERS, RESPECTIVELY. The bond energies in the two substances are discussed in terms of the possible molecular configurations. (Author)
