Calculation of absorption coefficients of gases at moderate temperatures

[a_potato]

Hello chaps,

I'm trying to calculate absorption coefficients of gases at moderate temperatures ie ranges in which diatomic gases (such as N2 orO2) are partially disassociated or ionised, therefore including molecular bands as well as continuum. Can anyone recommend some suitable reading material for me to get started on this problem. Many thanks

Thanks for that. Looks very comprehensive.
