摘要: A sensitive apparatus for transient spontaneous Raman studies of reactions in solution is described. The involves two Nd:YAG lasers coupled with multichannel, low noise spectral detection. technique applied to the chemistry aqueous triplet quinoxaline (1,4‐diazanaphthalene). spectra exhibit a sequence previously unobserved protonation reactions, showing be more complex than appeared earlier absorption studies. are acidic deuterium substitution protonated T1H+, and (apparently) diprotonated T1H2++.
