15N Isotope-selective infrared multiphoton dissociation of nitromethane by a free electron laser

Article abstract of DOI:10.1007/BF02495985

Successful experiments on the isotope-selective infrared multiphoton dissociation (IR MPD) of nitromethane molecules in the region of stretching vibrations of the NO₂ group have been performed for the first time under IR free electron laser (FEL) irradiation in a mixture with the natural content of the ¹⁵N isotope of 0.4%. The content of the ¹⁵N isotope in the products of NO dissociation varies within 0.1-1.696 as a function of the laser radiation frequency.
