Any Database for Dye Spectrophotometer Readings ?
I am looking for spectrophotometer readings for
tartrazine 1934-21-0 / 19140
malachite green orthochlorinated , basic blue 1 , setaglaucin , rhoduline blue 6g 42025
patent blue 3536-49-0 / 42051
crystal violet , basic violet 9 541-62-9 / 42555
erythrosine , acid red 51 561-63-1 / 45430
rose bengal , acid red 94 632-69-9 / 45440
Sigma and others did not help.
Try a Google search with the name of the dye and the word "spectra".
I did and found many different graphs, some from electrolysis effect on dye etc. I need what I can use for calculations.
Yes, check with Jim Browning.
Try this site - it even has data for CD-4 (this link may take you back to I agree page and then to the search page though if you havent been on there before)
Click I agree at bottom. Best to search by CAS number
