Resonance Energy Transfer between Carbon Monoxide and Oxygen Molecules Using Dye Laser Intracavity Absorption Spectroscopy.

Abstract

The dye laser intracavity absorption spectra of carbon monoxide and its mixtures with oxygen and helium in a plasma have been studied in the optical region between 5790 A and 6080 A. The purpose was to investigate possible resonant energy transfer between carbon monoxide and oxygen. A radio frequency discharge was used to excite the carbon monoxide gas to the upper vibrational levels of its ground electronic state from which optical excitation was performed by the dye laser to higher energy levels. The transition bands of the Fourth Positive System were observed in the CO spectrum where the initial states were identified as v=26 to 46 of ground electronic state. Anomalous effects in line intensities in the CO spectrum taken at 1 Torr were observed when oxygen was added at partial pressures between 0.01 and 2 Torr.
