Abstract
The decay rate of the excited state of the enol form of dibenzoylmethane (DBM) in
different solvents is measured directly using nanosecond light pulses. The observed
relaxation kinetics is explained by the formation of three intermediate forms of the
excited cis-enol form of DBM. The decay rates of the intermediates and their absorption
cross sections for λ = 266 nm are reported too.
