    The following factors can be considered as the factors governing the position of an IR absorption peak.

    * Strength of the bond

    * Masses of the atoms involved in the bond

    * The type of vibration being observed

    Explanation:

    Note that, when there is a quantum transition between two energy level, resulting in a situation where the band positions are to be expressed in terms of energy unit, it is known to cause IR absorption.

    A molecule is said to IR active, when there is a change in dipole moment, due to the vibration which occurs when IR radiation is absorbed.
