Abstract

We report the detection of short-lived species on electrode surfaces utilizing the enhancement of the Raman intensity afforded by proximity to silver electrodes. Using gated multiplexed detection we identify an photoproduct of flavinmononucleotide after excitation with 337nm radiation from a pulsed nitrogen laser. The product decays on the 700nsec time scale and is identified as the radical anion of the nucleotide.
