The natural abundance 13C-NMR spectra of a series of penicillins (penicillin V methyl ester, penicillin V, penicillin G, methicillin, oxacillin, cloxacillin, and dicloxacillin) were studied. The chemical shifts were assigned using the pulse Fourier transform technique with the aid of long-range carbon-13 hydrogen coupling. The previous assignments of pencillin V methyl ester were revised.
研究了一系列青霉素（青霉素V甲酯、青霉素V、青霉素G、甲氧西林、苯唑西林、氯唑西林和双氯西林）的天然丰度13C-NMR光谱。借助远程碳-13氢偶合，使用脉冲傅里叶变换技术确定了化学位移。修正了青霉素V甲酯先前的归属。
