scattering and capture cross sections? |
Where would one look for scattering and capture cross sections
for light in the range of IR through visible to UV, for various
chemicals
commonly found in the atmosphere? (O2, N2, H2O, CO2, etc.)

CRC Handbook, Earth Science section. "Oscillator strength" in
Google. Anything you do with the data will be a waste of bytes.

Doh! Should have looked in the CRC first.

Why do you say that?

I don't know about the present version, but the version
of CRC that I've had (66th edition) I'd say four out of
five times doesn't have the simple information that I
sometimes look for.
Let me see if I remember. Last time I referred to it
was a year ago for the bond length of ClH (or in your
terminology "HCl"). Something as simple as that didn't
exist in the damn book. I spent about 15 or 20 minutes
to finish looking over the long list with a magnifier
and ClH was not there! That is, it didn't even meet the
needs of a junior college student of chemistry.
***** that book. Unless they've given it some care by
now.
