✦ Synopsis

Singlet oxygen was generated in the gas phase at atmospheric pressure by the method of heterogeneous photosensitization. In vitro exposure of human lung WI-38 fibroblasts to gas-phase singlet oxygen resulted in sister chromatid exchange.

## Abstract The bimolecular rate constants __k__~q~ for quenching of singlet oxygen (^1^Ξ”~g~ state) by 26 different natural and novel synthetic carotenoids were determined at 37 Β°C in a mixture of chloroform and ethanol. The steady‐state technique used involves the generation of ^1^O~2~ by thermal
