Chemical shift trends in light atoms
In this chapter, the qualitative model described in Chapter 2 is applied to show systematic rationalizations in terms of chemical interactions that define well-known trends for chemical shifts corresponding to 13C, 15N, 17O, and 19F isotopes. The theoretical fundamentals for this approach are given...

| Sumario: | In this chapter, the qualitative model described in Chapter 2 is applied to show systematic rationalizations in terms of chemical interactions that define well-known trends for chemical shifts corresponding to 13C, 15N, 17O, and 19F isotopes. The theoretical fundamentals for this approach are given in Chapter 5. They could be a bit difficult to follow for readers who do not have a good training in physics and mathematics. However, this difficulty was intended to be overcome by resorting in Chapter 2 to describing this approach and providing "physically" several mathematical expressions and describing them in terms of familiar concepts employed frequently in different branches of chemistry and structural biology. The authors believe that once readers understand how easy this approach is and how it facilitates building pictorial representations of how several chemical interactions can be detected by means of high-resolution NMR spectroscopy, the initial problems will be overcome very soon. © 2013 Elsevier B.V. |
