Collisional broadening of oxygen fine structure lines: The impact of temperature

- Temperature dependence of the oxygen fine structure line widths was studied.
- Rotational dependence of the temperature exponents was analyzed.
- Results were compared with earlier experiments.
- Pressure shifts were found to be negligible.

The temperature dependence of self-, nitrogen- and air-broadening coefficients of oxygen fine structure lines was studied. Temperature exponents of a series of oxygen lines with rotational quantum number N ranging from 1 to 19 were measured with high accuracy for the first time. The obtained parameters were compared with the results of the earlier studies. This information is of high importance for atmospheric applications.
