Abstract
The optical ringing and the incoherent resonance decay of electronically excited (resolution ≈ 10^(−4) cm^(−1)) solids is observed using the technique of single-mode laser spectroscopy (SLS). The results show that localized states of pentacene in p-terphenyl, at 1.7 K, have a definite phase memory that can be destroyed only above 3 K due to the increased phonon population. Moreover, the optical coherence of the 0, 0 origin (at 16 882 cm^(−1)) gives a homogeneous linewidth of 40 MHz which is approximately 1100 the width of the vibronic origin, and orders of magnitude less than the “apparent” width of the resonance.
