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.

一氧化氮的温度依赖性15N NMR研究。

首次在不同温度下获得一氧化氮样品的¹⁵ N NMR数据。已获得液态和固态光谱。在前者中，化学位移以及自旋晶格弛豫时间的特征在于二聚反应的动态平衡。仅观察到（NO）₂二聚体的信号，而顺磁性NO对NMR参数有很大影响。通过T ₁弛豫和线宽分析，获得了单体与二聚体之间交换的相关时间的范围。SQUID测量结果证实了NMR分析。
