Rotational symetry control of electronic relaxation in ultracold geseous molecules: Optical-optical double resonance probe of the forbidden T_1- S_0 intersystem crossing in jet-cooled thiophosgene, Cl_2CS

摘要

Two-color optical-optical double resonnce studies of the T_1->S_0 interssytem crossing in jet-cooled thiophosgeen indicate that rotational symetry strongly infulences the efficiency of an inersystem crossing in symmeric molecules with low degress of rotational excitation.
