β¦ Synopsis
A unimolcculnr, laser-induced dissocktion reaction of s-tctradqe (C~H~NC), with a quantum yield of close to unity, was uSed to Separate citrogen I*/15 and Gabon E/13 isotopes. The sharp Q-branch.ofthe O-0 band of the 5515 4 absorption Stem of tctrZine gas irradiated for 1 minute p-,riods with a 10 mW cw twble dye lnser output that WZIS monochromatic to about 0.05 _4. Each of the decomposition products, found here to be tICiN snd Nz, 3s we!! 3s the starting materi& could be altered in isotopic composition, in cithcr direction, by sclcction of an appropriate laser wavelength. The largest one-step exuichnwnz ratio measured was 72. It makes possible mass wpzration at an efflcicncy of 1 j moles per k\Vh of laser energy.
