ABSTRACT:
The essentially monochromatic infrared radiation from a laser device with a frequency coincident with a vibrational absorption band of an isocyanide, for example, methyl isocyanide (CH.sub.3 NC), leads to isomerization to the corresponding nitrile, in this example, acetonitrile (CH.sub.3 CN). This isomerization is accomplished isotopically selectively for vibrational bands which exhibit an isotope shift. As a consequence, the enrichment and separation of nitrogen or carbon isotopes may be accomplished.
