Formaldehyde Vibrations

This page is dedicated to the IR vibrations of formaldehyde. There are three primary motions associated with this molecule. Two of these movements were a result of scissoring while the third vibration was a result of a wiggle in the carbon atom.

This is the movement for the peak around 1667 cm^-1

This movement is a scissoring movement. This movement is responsible for the vibration seen at 1667 cm^-1. It can be seen that the hydrogens scissor back and forth while the oxygen moves towads and away from the rest of the molecule.

This is the movement for the peak ar 1375 cm^-1 peak.

This is the movement associated with the vibration seen at 1375 cm^-1. The movement can be associated with the wiggle of the carbon atom.

This is the movement for the peak at 1336 cm^-1.

This is another scissoring movement. This movement can be associated with the movement seen at 1336 cm^-1. It is similar to the scissoring movement seen at 1667 cm^-1. The differences can be seen in the plane of scissoring of the hydrogen atoms and that the oxygen atom does not move.
