Abstract
The natural-abundance carbon-13 nuclear magnetic resonance spectra of the naturally occuring pyrimidine and purine nucleosides have been determined and completely analyzed. The carbon-13 chemical shifts obtained provide information on the electronic structure and qualitatively at least correlate well with the known chemical reactivity of these molecules. The carbon-13 shifts are in general far more informative than proton shifts for structural analysis of the nucleosides.
摘要
已测定并全面分析了天然存在的嘧啶和嘌呤核苷的天然丰度碳-13核磁共振谱。所获得的碳-13化学位移提供了有关电子结构的信息，并且至少在定性上与这些分子已知的化学反应性良好相关。对于核苷的结构分析，碳-13位移通常比质子位移提供的信息多得多。
