Luminescence of the oxygen dimole at the output of a chemical singlet-oxygen generator

The luminescence spectra of the singlet oxygen dimole, formed in a chemical jet — droplet generator, were recorded in the visible range of the spectrum with a resolution of 0.15 nm. In the gas-temperature range T = 150 — 350 K, the emission spectrum of the dimole was diffuse and had a half-width of 12 nm. The vibrational population of the oxygen at the output from the chemical singlet-oxygen generator reached 2%, which was an order of magnitude above its equilibrium value.
