This article from Khan Academy provides information about spectroscopy. Students will use equations to predict the wavenumber for different types of chemical bonds. This information is intended for organic chemistry students.

This article from Khan Academy provides information about how hydrogen bonding affects the shape of an IR signal (causing it to become broader and less sharp). This information is intended for organic chemistry students.

This article from Khan Academy provides information about spectroscopy. Students will understand how dipole moment determines the intensity of a signal in an IR spectrum.
