Near-ultraviolet chemiluminescence from the reaction of ammonia with hypobromite in aqueous solution
journal contribution
posted on 2006-11-01, 00:00 authored by Paul FrancisPaul Francis, Jacqui AdcockJacqui Adcock, Neil BarnettNeil BarnettThe chemiluminescence arising from the oxidation of ammonium chloride by sodium hypobromite in aqueous alkaline solution includes a series of peaks in the near-ultraviolet, which is not commonly observed in liquid-phase chemiluminescence. The dominant peak in that region has an intensity maximum at 292 nm and smaller peaks are observed at 313, 334 and 356 nm. The emitted photons are of similar energy to the Vergard–Kaplan transition of molecular nitrogen, a major product of this reaction. However, the spectral distribution is different to that of previously reported gas-phase chemiluminescence attributed to the Vergard–Kaplan transition.
