extinction coefficient

Post by tuphysic » Sun Nov 04, 2007 5:30 pm

Hi
Will somebody guide me how to calculate the extiction coefficient for a dye assembled onto Thin films (Langmuir-Blodgett films, thickness= one monolayer of dye on solid substrate)? Please reply

can you just scrape it off, weigh it, and then measure an absorbance specturm? extinction coefficient is based on the absorance of a 1% solution.
