A series of five‐, six‐, and seven‐membered 1,3‐dinitroso‐, 1‐nitroso‐3‐nitro‐, and 1,3‐dinitro‐1,3‐diazacycloalkanes were investigated by 1 H, 13 C, and 15 N NMR spectroscopy. Hindered rotation of the nitrosamine group leads to the existence of rotational isomers. The relative populations of rotamer forms are determined by steric and electrostatic interactions between nitroso groups and the remainder of the molecule, and by the size of the ring.
