A. Vlcek et al., BOND ACTIVATION BY MLCT EXCITATION OF ORGANOMETALLIC COMPOUNDS - PROMPT CO-PHOTODISSOCIATION FROM [CR(CO)4BPY], Coordination chemistry reviews, 132, 1994, pp. 167-174
Dissociation of an axial CO ligand from Cr(CO)4bpy under irradiation i
nto the MLCT absorption band is a prompt process that takes place from
directly excited vibronic levels of the 1MLCT state. Qualitative mode
l of such processes based on a vibronic coupling between MLCT and LF s
tates that activates promoting asymmetric vibration is proposed.
