Abstract

A new general method was developed suitable for measuring the lifetime of excited states in the condensed phase. This method is based on a multistep photoemission process in which the decay of an excited state generated by one pulse is measured by the use of a delayed probe pulse. The effective lifetime of a charge-transfer exciton state in tetracene was measured to be ∼20 ps.
