Let's say you are instructed to collect your distillate (condensate) in four separate containers,~1mL in each, during the fractional distillation of 4mL of a (1:1) cyclohexane-toluene mixture, and then obtain IR spectra for each fraction. How would the IR spectrum of the first 1 mL fraction look different from that of the last 1 mL fraction?
