Vacuum-Ultraviolet Absorption, Fluorescence Excitation, and Dispersed Fluorescence Spectra of BrCl

Article abstract of DOI:10.1021/j100358a016

Absorption and fluorescence excitation spectra of BrCl have been recorded between 137 and 180 nm with the use of synchrotron radiation.A pronounced resonance structure has been observed in the fluorescence excitation spectrum and it is attributed to coupling of ion-pair and Rydberg states.Dispersed fluorescence spectra have been obtained through vacuum-ultraviolet (vacuum-UV) excitation that display several oscillatory continua.These are assigned to emission predominantly from the lowest Ω = O⁺ ion-pair state (the E state) with probably some contribution from the f(O⁺) state of the second cluster.Fluorescence to four of the five O⁺ states correlating with the separated atomic J = 3/2 and 1/2 states is postulated.
