Abstract: The infrared multiphoton dissociation (IRMPD) of 1,4-dioxane, pyrrolidine and thiophene were studied with TEA CO2 laser. The mechanism involving breakage of carbon and heteroatom bonds were explored. The dependence of dissociation yield on laser energy was obtained. The laser dissociation threshold energy for dioxane, pyrrolidine and thiophene are 0. 85, 1.0 and 1. 5 J/cm2 respectively.

Key words: The infrared multiphoton dissociation, 1,4-Dioxane, Pyrrolidine, Thiophene
