Spin -Orbit Coupling in the O-2 Anion
Abstract
We could resolve the spin-orbit splitting of 160 ± 4 cm-1 in the 2II ground state of O2- anions by high resolution photodetachment photoelectron spectroscopy. The observed splitting is in good agreement with the theoretically derived value. Our directly measured electron affinity of O 2 is 450 ± 2 meV and deviates within experiment errors from previous values. kHz repetition rate was applied to avoid space charge and improve electron energy resolution in a time-of-flight electron energy analyzer.
