ABSTRACT:
Methylamine (CH.sub.3 NH.sub.2) is dissociated into CH.sub.3 .multidot. and NH.sub.2 .multidot. radicals when irradiated with the output from an infrared laser. Ammonia (NH.sub.3) is then formed inherently through radical and molecular collisions. By tuning the laser to the appropriate frequency, the dissociation process is isotopically selective. As a consequence, ammonia, or other nitrogen containing compounds, are obtained which are selectively enriched in .sup.14 N or .sup.15 N. Carbon isotopes may be separated with essentially the same technique. .sup.
