State dynamics of (COF)2 excited to single rotational levels of different vibronic states of the A∼1Au electronic state

Excited state dynamics of oxalylfluoride was studied. External electric field influence on the state dynamics of electronically excited (COF)2 was analyzed. External electric field was shown to affect the internal conversion transitions. A previously developed theory was applied to (COF)2 excited into single rotational (00,431) and (5171,413) levels of the A∼1Au state. Strong electric field effect on the IR emission from the ground-state vibrational transitions was detected and interpreted for the (00,431) level. The electric field effect was also observed for the (5171,413) level, accompanied by the COF radical formation instead of the IR emission.
