Establishing the Backbone Connectivity in an Organic Molecule

In Section 9.3.1, the problem of assigning the many resolved resonances in a ID MAS spectrum was mentioned, and ID spectral editing methods were introduced. In this section, we describe homonuclear 2D correlation experi- 

In the first class of 2D correlation experiments described here, SQ 

As a specific example. Fig. 9.17 shows the region corresponding to the and aliphatic side-chain carbons of a SQ—SQ correlation spectrum of 

By using very-high magnetic fields, ever larger biopolymers are becoming accessible to solid-state NMR. As an example, Fig. 9.18 presents a SQ—SQ cor-
