This paper reports the first use of radiation derived from a TEA carbon dioxide laserby nonlinear upshifting techniques (second harmonic generation) in initiating multiphotonabsorption and dissociation. The frequency doubled CO 2 laser has frequencycoverage from 2180–1750 cm –1 . This frequency region is of importance as it allowspumping of the fundamental stretching modes of organic carbonyl groups (anhydrides,acyl chlorides and strained cyclic ketones), inorganic carbonyl groups, and carbontritiumbonds. The laser has been used to excite cyclobutanone in the region of thecarbonyl stretch. Efficient multiphoton absorption and two channel dissociation areobserved. The product array is consistent with that observed upon excitation at 10 μm.
