| Abstract: | 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 the15N isotope of 0.4%. The content of the15N isotope in the products of NO dissociation varies within 0.1–1.6% as a function of the laser radiation frequency.
