Excited State Relaxation Dynamics in Benzophenone and <i>meta</i> -Methyl Benzophenone Revealed by Time-Resolved Photoelectron Spectroscopy

state minima over a time constant of 6-20 ps and finally funnels down to the triplet manifold via intersystem crossing. In addition, methyl substitution effects and excitation energy dependence on the excited-state dynamics of benzophenone are also discussed. This experimental study provides valuable insights into the decay dynamics of photoexcited benzophenone.
