详细介绍了多个频率同时演化到一个核磁共振脉冲序列的同一时间段的实现。时间共享（TS）版本最有用的逆二维核磁共振实验（TS- hmbc, TS- hsqc, TS- hsqc - tocsy，和TS- hsqmbc）提出并说明了同时获取H-1/C-13和H-1/N-15核磁共振光谱。从单个核磁共振实验中并行获取多个光谱的主要好处是节省了光谱仪的时间，并在每时间单位内提高了灵敏度增益，实现了多个和互补的信息。(C) 2010 Wiley期刊公司概念主要原因Part A 36A: 1-23。2010.
Details on the implementation of the simultaneous evolution of multiple frequencies into the same time period of a NMR pulse sequence are introduced. Time-shared (TS) versions of the most useful inverse 2D NMR experiments (TS-HMBC, TS-HSQC, TS-HSQC-TOCSY, and TS-HSQMBC) are presented and illustrated for simultaneous acquisition of H-1/C-13 and H-1/N-15 NMR spectra. The major benefits associated to the parallel acquisition of multiple spectra from a single NMR experiment are spectrometer time savings and the achievement of multiple and complementary information with improved sensitivity gains per time unit.
