Notes:
Previous resonance Raman studies with the spinning cell technique indicated that the L550 intermediate gave a doublet at 1552 and 1539 cm-1 for the C=C stretching mode whereas the results from the flow cell technique suggested that the two bands arise from different intermediates on the basis of different kinetic behaviour. This study has explored the origin of the discrepancy by applying both the double-beam flow apparatus and the spinning cell to an identically prepared sample for observing transient resonance Raman spectra. It was found that the presence of a very small amount of dark adapted species caused the apparent differences in the kinetic behaviour of these two bands.
