โฆ Synopsis
It is proposed that photo-induced decarbo\ylatlon of pyruvic acid occurs via electron transfer from an excited to a ground-state molecule. Quantum yields of triplet production at 295 I( in deoxygenated benzene, acetonitrile and water are 0.65,0.88 and 0.22. The triplet state of naphthalene is quenched by pyrutic acid and It 1s suggested t!mt this occurs via electron transfer.
