| Abstract: | 14N NMR was applicd to the study of the pH-dependent structures of histidine in aqucous solutions. 14N spin-lattice relaxation times(T1) were measured by inversion-recovery method.According to the spectra and the T1 data,different structures of histidinc in aqucous solutions were determined. |

| Keywords: | Histidine pH value 14N NMR Relaxation |
