WebStrong (1)H- (1)H coupling can significantly reduce the accuracy of (1)J (CH) measured from frequency differences in coupled HSQC spectra. Although accurate (1)J (CH) values can be extracted from spectral simulation, it would be more convenient if the same accurate (1)J (CH) values can be obtained experimentally. WebThe HSQC-TOCSY experiment [13] is another simple but complementary extension of the HSQC experiment which provides the simultaneous information of 1 H and 13 C chemical shifts into a complete J-coupled spin system, offering a relevant interest in the analysis and unambiguous assignments of complex spin systems. famous quotes by joe biden
