Lowest Singlet and Triplet States of the Oxyallyl Diradical

Lowest Singlet and Triplet States of the Oxyallyl Diradical

Small S–T splitting: The photoelectron spectrum of the oxyallyl radical anion (see picture) reveals that the electronic ground state of oxyallyl is singlet, and the lowest triplet state is separated from the singlet state by only (55±2) meV in adiabatic energy.
