1H-13C HSQC spectrum of the VPS-PS with 1H NMR trace.Fitnat, Yildiz
1H,13C的异核二维相关谱由13C检测(HETCOR)变为1H检测(HSQC),优点是干扰的杂峰少,但检测的灵敏度低。()A.正确B.错误
1H and 13C NMR spectroscopic data of 20 new non-symmetrical compounds were assigned by a combination of 1D and 2D NMR experiments (DEPT, HSQC, and HMBC). These compounds contain a 4-(N,N-dimethylamino)- or 4-(pyrrolidin-1-yl)pyridinium moiety and a 3-nitro-, 3-amino-, or 3-...
1H-13C HSQC-NMR detects a carbon and its directly-attached protons (CH bond), thus would detect the disappearance of CH, if the proton is electrophilically substituted by I to form the CI bond. The objectives of this study are two-fold. The first objective is to identify CI formation ...

2D 1H–15N or 1H–13C NMR spectra, such as HSQC, provide adequate resolution within a reasonable time for data collection. Therefore, they have been commonly used to identify drug-binding sites, including for anesthetics (Bondarenko et al., 2013, 2014, 2008; Mowrey, Liu, et al., 2013)....
