Abstract
The p P(k=9) magnetic-dipole transition of the oxygen 0-0 vibrational band of the red system b 1? g + <-X 3? g - was observed with absorption spectroscopy using a tunable CW diode laser. A systematic investigation of the self-collisional broadening was performed for different gas pressures and temperatures. The temperature dependence of the self-broadening coefficient was determined to be T^ -(1.02±0.05). Our results are of interest for collisional theory and as reference data in atmospheric monitoring applications.File in questo prodotto:
