What is the nuclear relaxation treand in Solid state NMR of C and N?

Vijayakumar Samiyappan @Vijayakumar-Samiyappan

22 March 2022 0 9K Report

In the case of solution state NMR excited nuclei relax back to ground state either by spin-spin or spin-lattice relaxation. The influence of adjacent nuclei in signal intensity is seen in hydrogen attached carbon and quaternary carbon in proton decoupled 13C NMR.

Such trend is similar in solid state NMR in C and N nuclei?
