Enrichment of nitrogen isotopes by induced isomerization of isocyanides
Patent
·
OSTI ID:5723339
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.
