✦ Synopsis

A theory of a desorption induced by an infrared laser 1s developed. The laser excites an anharmonic molecule to the fust exctted level and higher vibrational levels are achieved by mtermolecular energy transfer. Once the molecu!z: is extired to the higher levels It may desorb. It 1~. shown that a frequency dependence of the yield from the Rtb excited level IS proportional to the Rth degree of the corresponding Lorent&n. l% fi eld is proportional to the Rth degree of the laser field power and is saturated when the number of adsorbate monolayers fi increasing.
