A high-performance liquid chromatographic method was developed for the simultaneous determination of azobenzene, hydrazobenzene, and four other decomposition products in phenylbutazone injectable formulations. Separation was achieved on a C18 column, with 0.1 M Tris-citrate buffer (pH 5.25) and acetonitrile (52:48)

A quantitative model of mixed-valence excited-state spectroscopy is developed and applied to 2,3-diphenyl-2,3-diazabicyclo[2.2.2]octane. The lowest-energy excited state of this molecule arises from a transition from the ground state, where the charge is located on the hydrazine bridge, to an excited
