Time-resolved resonance Raman spectroscopy difference spectra

Figure 5. Resonance Raman spectra (1400-1700 cm ) of transient intermediates produced in the pulse radiolysis of a 2 mM aqueous solution of p-methoxyphenol (N20 saturated pH 11). Key a-d, the spectra obtained at different times (At) after the electron pulse d, the spectrum of p-benzosemiquinone anion (marked A) and e, the spectrum of tp-methoxyphenoxy radical (marked B) obtained after subtracting dfrom a. This figure illustrates the use of time-resolved resonance Raman spectroscopy to time-resolve the spectral overlap between transients decaying at different time scales.
