i'revious investigations have shown that eucarvone (1) is slowly converted photochem1cally into a mixtllre of Isomers (2-S) whose composition is solvent -de?eTdent. 4s,s F"echanisms have been suggested for these isonerizations, al- thollqh no work hss been resorted specifying the nature of the excit
