Abstract : A method of separating and concentrating the 15N isotope from natural abundance nitric oxide(NO) comprising mixing natural abundance nitric oxide in an appropriate mole ratio with carbon dioxide(CO2); 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.
