Abstract

For the first time, ¹⁵N NMR data are obtained for a sample of nitric oxide at various temperatures. Spectra have been obtained in the liquid and solid state. In the former, the chemical shift as well as the spin-lattice relaxation time is characterized by the dynamic equilibrium of the dimerization reaction. Only the signal of the (NO)₂ dimer is observed, while the paramagnetic NO has strong influences on the NMR parameter. From T₁ relaxation and linewidth analysis a range for the correlation time of the exchange between monomer and dimer is obtained. SQUID measurements corroborate the NMR analysis.
