摘要
A method of separating and concentrating the .sup.15 N isotope from natural abundance nitric oxide (NO) comprising mixing natural abundance nitric oxide in an appropriate mole ratio with carbon dioxide (CO.sub.2); irradiating the NO--CO.sub.2 mixture with coherent laser light of a desired wavelength, thereby selectively exciting the nitric oxide species containing the .sup.15 N isotope, which subsequently reacts with the carbon dioxide to form nitrogen dioxide (.sup.15 NO.sub.2); and separating said nitrogen dioxide (.sup.15 NO.sub.2) from the gas mixture.
