    • ex = 390 nm this corresponds to a dip in the transient absorptoin spectrum at about 450 nm. This was found to be stimulated Raman scattering due to the solvent only. This interpretation was demonstrated by setting the excitation wavelength of a fluorometer to the laser excitation wavelengths and measuring the Raman scattering from a cuvette of the appropriate solvent. The width of the stimulated Raman line was limited by the monochromator band-pass. Therefore, the data showing the ground state bleach are selected slightly off the maximum of the absorption spectrum (450 nm) in order to avoid confusion over this large artifact. A similar feature was observed for data collected in formamide.
