ABSTRACT:
Vapor of dicyclopentadienyl zirconium dicyanate is irradiated by a laser beam of a CO.sub.2 laser tuned to the stretching frequency of the .sup.S Zr-O-C bond of the dicyanate where .sup.S Zr is a selected isotope of zirconium. The excited component of the irradiated dicyanate including the .sup.S Zr is decomposed and is separated from the remainder. The dicyanate is readily prepared in large quantities, resists hydrolysis, sublimes at a temperature well below its dissociation temperature, and has a lower molecular weight than other proposed compounds such as dicyclopentadienyl zirconium diisopropoxide, and dicyclopentadienyl zirconium-di-tert-butoxide
