Abstract :
We report on experimental and theoretical investigations of matrix-isolated molecules of MePTCDI, presenting transient absorption spectra obtained with ultrafast pump-probe spectroscopy. The experimental transient absorption spectrum is consistently explained by highly-correlated quantum-chemical calculation methods.
