Platinum‐loaded microporous aluminophosphate molecular sieves (Pt‐AlPO 4 ‐5) were synthesized and studied as catalysts for promoting tritium isotope labelling by exchange between tritium gas and aromatic, heteroaromatic and aliphatic hydrocarbons. The presence of the Pt metal considerably enhanced the activation of the tritium gas. Detailed isotope orientation patterns, as determined by 3 H nmr spectroscopy, showed that the AlPO 4 ‐5 component of the catalyst dominated the exchange reactions, but some influence of the Pt metal was apparent with some substrates.
