Infrared Vibration-Rotation Spectroscopy of HCl and DCl
... Both the vibrational and rotational motions of a molecule are quantized. Vibrational motion describes the internal motion of an atom within a molecule relative to other atoms. In a diatomic molecule, this motion occurs along the bond and is called a stretching. This motion depends largely on the str ...
