Kanosecond flash photolysis of 1,2-and 1,8-dinitronaphthalenes (1,2-DNOzN; 1,8-DN02N) in nonpolar and polar solvents shows transient species with absorption maxima and lifetimes dependent on solvent polarity. In deaerated n-hexane the absorption maxima and lifetimes ( l / K ) are 490 nm and 1.0 psec
Many investigations have been made on the polarographic reduction of chalcone and its heterocyclic analogues 1-1ยฐ. Thus, Tirouflet and Corvaisier 11 described the reduction of the pyridyl analogues of o-hydroxychalcone in buffered solutions of 40~ isopropyl alcohol. Under these conditions, isomeric
