Part I: Understanding String Theory

One of the most intriguing characteristics that string theory displays is that it unifies what is known as the four fundamental forces of nature. These forces, gravity, the electromagnetic force, the weak nuclear for ...

7 Spin-Lattice Relaxation - Quad-NMR on solids by D. Freude and J

For spin‐lattice relaxation of quadrupole nuclei in solids, the static part of the quadrupole interaction, which causes a shift of the Zeeman levels, is most often large enough to inhibit the spin exchange between different transitions. Thus, a spin temperature will not be established as fast as f ...
