absorption coefficients

[Kai Schmengler]

Dear all!

I determined Km-values of an enzyme with the substrates guaiacol and
potassium iodide. Unfortunately I chose wavelengths (near published
ones) I didn’t have the absorption coefficients (extinction
coefficients) for. Now I’m looking for a table or papers in which those
coefficients could be published. The wavelenghts were 405 nm for
potassium iodide and 450 nm for guaiacol.


Thank you very much.
