Beschreibung:
We combine our two recent theoretical approaches for electronic relaxation T1→S0 and vibrational relaxation processes in thiophosgene (SCCl2) to provide a more detailed picture of the intersystem crossing (ISC) and phosphorescence from the first triplet T1. Our analysis shows that ISC is not a true irreversible decay and should lead to violent phosphorescence quantum beats that could be observed experimentally.
