✦ Synopsis

Femtosecond time-resolved transient grating experiments reveal an extremely fast relaxation process in pyrene excimer-forming crystais following electronic excited-state production via two-photon absorption. We interpret this as relaxation of the initially excited, delocalized exciton into the self-trap~d, distorted excimer state.
