Relationship between photochemical mechanisms and chiral molecules

Click For Summary
SUMMARY

The discussion centers on the influence of circularly polarized light (CPL) on the chirality of molecules, specifically whether left-handed CPL consistently produces levorotatory molecules. It is established that while CPL can promote chiral asymmetry in photochemical reactions, the effects observed since the 1970s have been minimal. The relationship between CPL and optical activity is questioned, with the suggestion that any correlation may be coincidental rather than systematic. The inquiry highlights the historical context of these observations and their relevance to the origins of life.

I'm way outside my realm of knowledge here so perhaps I need some help polishing my question or the concepts behind it. Thank you for your patience.

Does the orientation of circularly polarized light (CPL) as a reaction mechanism influence the chirality of the molecule in a general manner, such as left handed circularly polarized light creates levorotatory molecules? More importantly, does CPL influence the optical activity in a similarly consistent manner?

L/D chiral conventions are based on nomenclature rules and therefore I suspect any influence would be coincidental. How would I Google or go about collecting data for my question?

I do know that starting in the 1970s if not earlier many observations have been made of chirally asymetric photochemical reactions promoted by circularly polarised light, though as far as I know the effects have always been quite small.

More often than not the work is done with origin of life very much in mind.
 
Thanks for the response. The relationship light has with life has been on my mind recently.
