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...
