## Abstract Chemical polarisation of ^13^C and ^15^N nuclei in the thermal decomposition of diazoaminobenzene has been investigated. Most of the polarised products with the exception of benzene result from cage recombination processes, and both the ^13^C and ^15^N true nuclear polarisation coeffici
