Chemical periodicity on the µs time-scale of an intermediate following ns flash photolysis of benzilic acid sensitised by oxidising metal ions
Abstract
The 347 nm ns flash photolysis of acetone solutions of benzilic acid containing sensitising metal ions (Ag+, Cu2+, Fe3+ and, less markedly, HgCl2) above certain photo-oxidant concentrations produces a structured, transient absorption spectrum spanning the entire visible spectrum which displays complex, but reproducible oscillatory behaviour.
