Absorption Coefficient of Acetonitrile in the Visible Spectrum

[sicjeff]

Does anyone know the molar absorption coefficient for acetonitrile? I need to know what wavelength the coefficient is at of course as well. Hopefully I can find one in the visible spectrum. My department does not have an ultra violet spectrophotometer.

I guess I should pick easier thermodynamic experiments

Acentonitrile does not have an appreciable visible absorbance.

Look in a Fisher catalog for the Optima grade. You will see that it has no appreciable absorbance down to 200 nm (deep in the UV!).

Absorbance (200nm) <= 0.07

thank you. I guess I will have to pick something else. Could anyone suggest a liquid immiscible in water that absorbs in the vis spectrum?

 

[chemisttree]

What is the solute and what, in general terms, are you trying to investigate?

BTW, acetonitrile is completely miscible in water. Good thing it didn't work out, yes?

i would suspect that acetonitrile is uv active
