摘要：

Triplet-triplet-induced absorption has been measured in pump-probe experiments on polydiacetylene DCH films. The excitation spectrum of the induced absorption has been obtained for pump photon energies in the range 1.95-3.40 eV. Above 2.15 eV the induced absorption depends linearly on the pump intensity. Below this energy a quadratic law is valid showing that triplet excitons are produced in a two-step process for the lower photon energies.
