The IR spectrum of aliphatic alcohols have a distinctive O-H stretch in the range of 3300 to 3400 cm -1. This peak tends to be very strong and very broad. This exact position of the peak is dependent on the amount of hydrogen bonding in the alcohol. In addition alcohol have a strong C-O stretch near 1000 cm -1.
