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。
