摘要：

We show with time-resolved all-optical spectroscopic techniques like pump-probe and grating scattering that a hydrogen-bond cleavage between Coumarin 102 and several hydrogen donors occurs in 170 fs. We also observe additional dynamics on longer time scales due to reorganization of the solvent shells. (C) 1999 Elsevier Science B.V. All rights reserved.
