Evidence for surface activation in the photolysis of adsorbed lead tetraethyl
Abstract
Condensed multilayers of PbEt4 decompose when irradiated with u.v. light of wavelength 254 nm to give gaseous C2 and C4 hydrocarbons and a lead film; adsorbing PbEt4 on a photodeposit of Pb generates a more reactive species which is active in photolysis at longer wavelengths (280–290 nm).
