Abstract: The P-P(k=9) magnetic-dipole transition of the oxygen 0-0 vibrational band of the red system b(1) Sigma(g)(+) <-- X(3) Sigma(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.
