用核磁共振技术测量了液态水中短寿命核17N(i= 1/2，t1/2= 4.17s)的核磁共振谱，以阐明氮离子注入水中形成的化学物种。我们已经将光谱分辨率提高到了5ppm，与之前的研究相比，这大约是之前研究的1/40。得到的光谱形状表明，它可能由多条共振线组成，而不是由一条线组成。根据目前的结果，讨论了有关水中氮的化学状态的一些可能性。
Nuclear magnetic resonance (NMR) spectrum of the short-lived nucleus17N (I= 1/2,T1/2= 4.17s) in liquid water was measured by means of theβ-NMR technique to clarify the chemical species formed by nitrogen ions injected into water. We have improved the spectral resolution to 5ppm in the full width at half maximum which is about 1/40 times compared to the previous study. The shape of the obtained spectrum indicated that it may consist of multiple resonance lines rather than a single line. Some possibilities regarding the chemical states of nitrogen in water are discussed based on the present result.
