I'm not really sure if this is right place to post this since I am new here.  I was wondering if anyone can help me figure out how to calculate the nitrogen concentration in a diamond at the A aggregate from FTIR spectra? I have think I understand which parts of my sample to plug in to a Beer's Law formula, but I'm uncertain what determines my path length should be. Can I use Beer's Law to solve this problem?
