Picosecond time-resolved resonance Raman spectra of pHP DEP (24, X = diethyl phosphate) obtained with a 267 nm pump and 200 nm probe wavelengths in a H2O/CH3CN (1:1) mixed solvent. The resonance Raman spectrum of an authentic sample of p-hydroxyphenylacetic acid recorded with 200 nm excitation is displayed at the top. Reprinted with permission from ref (96a).
