Based on analysis of the IR spectra for each unknown compound determine the absorption bands with wavenumber, intensity, and shape. Do for both regions. Intensity can be described as strong, medium or weak. Shape can be described as sharp or broad.

For example: The IR spectrum of liquid unknown 1 exhibited a strong, broad absorption band at 3200 cm-1 and a weak but sharp absorption band at 2975 cm-1. Other notable absorption bands in the IR spectrum for 1 were at 1000 and 950 cm-1.
