Abstract
The present invention relates to a method for enrichment of oxygen 18, which comprises the steps of optionally adding a hydrocarbon to a saturated aliphatic ether other than dimethyl ether and/or a saturated cyclic ether as an oxygen 18-containing starting material, irradiating the material(s) with laser light to induce oxygen 18 selective photodecomposition and separating oxygen 18-containing products from the photodecomposed products. Oxygen 18 enriched compounds obtained by the present invention can be used as tracers and the like.
