On irradiation in solution in hydrogen-donating solvents, methyl and ethyl pyruvale react through their excited singlet and triplet states to yield a pair of isomeric radicals. Each isomer is formed via both pathways, but in some solvents one is produced predominantly from the singlet state and the
## Abstract The operation and efficiencies of molecular or polymer organic lightβemitting diodes depend on the nature of the excited species that are formed. The lowest singlet and triplet excitons display different characteristics that impact on the quantum yields achievable in the devices. Here,
