High-resolution Fourier transform nuclear magnetic resonance was used to observe the natural abundance (13)C spectrum of a 0.02 M solution of bovine pancreatic ribonuclease A. Peaks assignable to only three carbons were easily observed after 10 hr of signal averaging. A number of tentative assignments were made. As expected, the (13)C spectrum was appreciably richer in detail than the corresponding proton spectrum. Natural abundance (13)C Fourier transform nmr appears to be a practical tool for the study of biopolymers in solution.
使用高分辨率傅里叶变换核磁共振来观察0.02M牛胰核糖核酸酶A溶液的天然丰度（13）C谱。在信号平均10小时后，很容易观察到仅可归因于三个碳原子的峰。进行了一些初步的归属。正如预期的那样，（13）C谱在细节上比相应的质子谱丰富得多。天然丰度（13）C傅里叶变换核磁共振似乎是研究溶液中生物聚合物的一种实用工具。
