hi guys, can you tell me where ( website or books) to find absorption coefficients of organic compounds according to wavelengths (1000-2000nm)?? thank you very much! | ||

The best modern compendium that I know of is Jerry Workman's "Handbook of Organic Compounds", Academic Press (now Elsevier, I think) (2001). It's expensive, but it's a three-volume set that includes absorbance spectra for NIR, Mid-IR, Visible, UV and Raman spectra. Howard \o/ /_\ | ||

I think that you might want to look for absorption coefficients in older texts, because that was when NIR was being used for quantitative analysis directly. Bob Goddu's 1960 chapter in "Advances in Analytical Chemistry and Instrumentation", Volume 1 edited by Charles N. Reilly; Interscience Publichers, NY, gives many molar absorptivities in solutions (usually carbon tetrachloride). There is also a similar chapter in an IR book by Conway. Alternately, maybe I can photocopy and mail you some of it, if you give me an address. Please contact me at [email protected] if you would like to see these pages. |
