[edit] Moved text
I moved the contribution from 'Dinesh Pathak Ph D student GND University Asr' into the main body of the text as a new 4th paragraph and cleaned up some of the spelling. Mattgrommes 21:30, 3 August 2006 (UTC)
[edit] Molar (decadic) absorption coefficient
IUPAC recommends that ε be called the molar (decadic) absorption coefficient. See [1], [2], and especially [3].

[edit] Definition (renamed from Numerical definition)
I have made a somewhat feeble attempt to clarify and tighten up the lead paragraph; I also changed the section title, "Numerical definition", to just "Definition".
There remains some confusion about the consistency of the units and the terminology, which I need to refer to my textbooks to straighten up (is it per meter, or per gm/cm^2, etc?) Someone more expert about the terminology and the whole field of radiative transfer is really needed to do this better. Improved co-ordination between this page and the article on radiative transfer, within the general subject of which opacity is just one important concept, also needs to be addressed.
The actual calculation and tabulation of opacities, generally of plasmas and stellar atmospheres, is a major field of endeavor in itself in astrophysics (& I suppose in many other fields), and may deserve separate treatment, or a section here with references to the literature.
As it is the article seems fragmented and disorganized, though I see many good chunks. Needs TLC from someone, I think. Wwheaton (talk) 17:59, 19 February 2008 (UTC)
