15N nuclear magnetic resonance chemical shifts are shown to be highly sensitive to site-selective diamagnetic metal ion binding for the nucleosides adenosine, cytidine, and guanosine. Conclusions regarding preferred complexation sites are compared with results derived from other physical measurements, and with expectations based on electron density calculations.
