Heteronuclear single-quantum coherence HSQC spectroscopy

Further 2-D H total correlation spectroscopy (TOCSY) anal3rsis of fire humate from the cellulose treatment indicates that this region is rich in aCH and CH2 of amino acid residues phis CH/CH2 of polysaccharides (Figure 6). These assignments were made based on the proton covalent connectivity and chemical shift information acquired from the TOCSY spectrum, and are in agreement with the 2-D heteronuclear single quantum coherence (HSQC) analysis... [Pg.146]

The main emphasis of current carbohydrate structural analysis is the applicability of modern multi-dimensional NMR for solving the two crucial problems in complex carbohydrate structural analysis, namely, the elucidation of the sequence of glycosyl residues and the solution conformation and dynamics of a carbohydrate (150). Techniques include 2D Total Correlation Spectroscopy (TOCSY), Nuclear Overhauser effect spectroscopy (NOESY), rotational nuclear Overhauser effect spectroscopy (ROES Y),hetero-nuclear single quantum coherence (HSQC), heteronuclear multiple quantum correlation (HMQC), heteronuclear multiple bond correlation (HMBC), and (pseudo) 3D and 4D extensions. [Pg.232]

Similarly, PPI dendrimers have shifts that are very similar for each repetitive layer, and to completely assign these strac-tures more complex methods such as 2D-NOESY (two-dimensional nuclear Overhauser enhancement spectroscopy) and 3D-NOESY-HSQC (HSQC, heteronuclear single quantum coherence) have been used. These methods will be discussed in the following. ... [Pg.130]
