摘要：
Infrared multiphoton absorption is introduced as a method of direct heating of gas phase molecules prior to field ionization. This approach appears to be a very effective way to increase fragmentation following field ionization of the vibrationally excited molecules. Comparison is made with the method of electrical heating of the emitter which results in an indirect heating of the molecules prior to field ionization.
