Organic Chemistry

I just finished an organic chemistry lab experiment on separating and analyzing an unknown acid/neutral compound mixture using extraction, recrystallization, TLC, melting point analysis, and IR spectrum.

In the instructions, "Obtain an IR spectrum for each of your recrystallized compounds. Analyze each spectrum, and assign the principal vibrational bands in each." I identified the unknowns and obtained their recrystallized IR spectrums, but I don't know what how I am suppose to assign the principal vibrational bands.

Thank you in advance!
