Hi Randy,
a list of extinction coefficients is at
McNamara 2007 Fluorophore Data Tables
at
http://home.earthlink.net/~pubspectra/
Use Excel's search command (try full name, if that does not work, try
DEAC, or coumarin ... I found the E.c.'s below by searching for
coumarin). I've pasted a subset below.
Pacific Blue
3-carboxy-6,8-difluoro-7-hydroxycoumarin
29,500 (QY = 0.75)
Alexa Fluor 350 (Alexa350)
7-Amino-4-methyl-6-sulfocoumarin-3-acetic acid
15,500
AMCA and AMCA-X
(Coumarin)
19,000
7-methoxycoumarin-3-carboxylic
acid
26,000
7-diethylaminocoumarin-3-carboxylic
acid
56,000 = DEAC (though you wrote dimethyl [DMAC?], not diethyl
[DEAC])
D-AMCA
56,000
Hydroxy coumarin
(HYCO)
36,000
7-amino-4-methylcoumarin (row
4382)
18,000 (QY = 0.18) = DAMC?
6-chloro-7-hydroxy-coumarin-3-carbamide (row
4552)
44,000 (QY = 0.93)
Anyone looking for fluorescent protein data can find a few in the Excel
sheet at top, more in the
Data file at
McNamara G, Boswell C (2007) A Thousand Proteins of
Light: 15 Years of Advances in Fluorescent Proteins.

Educational Topics in Microscopy (volume 3), in press.

Does anyone know if there is (and where I can find) a comprehensive
list
of extinction coefficients for fluorescent compounds.
At the moment I am looking for the extinction coefficient of DEAC -
dimethylaminocoumarin dye.
