A STUDY OF ~3H NMR SPECTROSCOPY OF TRITIUM LABELLED IMIDAZOLE AND ITS DERIVATIVES

The positions and contents of tritium labelled imidazole and its derivatives by catalytic tritiation are determined by ~3H NMR spectroscopy. The results show that the exchange process can get the generally labelled compounds at the range of 8—180 h and 85—200℃ by using PtO_2 as the catalyst and tritiated water as a source of tritium.
