Abstract
Partial photoresolution of [Formula: see text], Cr(C2O4)2phen−, and [Formula: see text] by irradiation with circularly polarized light from an argon ion laser and 496.5 or 514.5 nm is reported. Steady states corresponding to 1–2% resolution are achieved. They are in agreement with predictions from known circular dichroism and the assumption that differential isomerization is simply a consequence of differential absorptivity of the enantiomers.
