Study on the position of tritium in aromatic molecules labelled by different methods. A developed high temperature radio-gas chromatography permitted fast and reliable analysis of toluene derivatives for the purpose of obtaining information on tritium distribution in the toluene molecule. The comparison of the various methods of H 3-labelling showed the specific influence of the energy pick-up. The results were also compared with those in the nitro- and chloro-benzene system. The gas exposure technique, electric discharge, irradiation by U-V light, high energetic recoils and also microwaves were applied in this investigation. Whereas in the case of toluene the gas exposure techniques favour the substitution in the ring, the electric discharge and microware treatment leads to preference of the methyl group. The G$\gamma$-value (number of H$^{3}$ atoms incorporated in toluene per 100eV absorbed) was found to be nearly independent from the H$^{3}$- or toluene pressure, but to increase with growing amounts of tritium. |
