Abstract:

A method of separating and concentrating the 15N isotope from natural abundance nitric oxideNO comprising mixing natural abundance nitric oxide in an appropriate mole ratio with carbon dioxideCO2 irradiating the NO-CO2 mixture with coherent laser light of a desired wavelength, thereby selectively exciting the nitric oxide species containing the 15N isotope, which subsequently reacts with the carbon dioxide to form nitrogen dioxide 15NO2 and separating said nitrogen dioxide 15NO2 from the gas mixture.
