## Abstract The PMR spectrum recorded during the reaction of __tert__‐butylmagnesium chloride with __p__‐chlorophenyl diazonium tetrafluoborate shows the CIDNP effect in the spectra of the the reaction products. Enhanced absorption and emission (the multiplet effect) has been observed for the proto
