O2 Microwave Spectrum

This shows an example of a microwave spectrum using a magnetic moment. The values are taken from G.Yu. Golubiatnikov and A.F. Krupnov, J Molec. Spectrosc. 225, 222 (2004), but with γH = 0, which gives a better fit to the experimental data.
.
It gives good, but not exact agreement with their calculated values. The values calculated by PGOPHER have been checked against the explicit formulae given in Rouille at al, J Molec. Spectrosc. 154, 372 (1992) so the discrepancy is probably due to a slight difference in the method of calculation.
