Abstract

Electron-impact excitation of sulphur dioxide at energies greater than the threshold energy (3.85 ± 0.4 eV) results in optical emission mainly from the B~ ¹B₁ state of sulphur dioxide. Optical emission excitation functions have been determined at several wavelengths and demonstrate that the primary excitation process(es) is dominated by production of optically forbidden triplet states. The observed emission arises from intersystem crossing from these triplet states into the fluorescing B~ ¹B₁ state.
