Broadband decoupling and spin-locks

Numerous such composite pulse decoupling sequences have been developed along these lines over the years (Table 9.2), the most widely used being WALTZ-16 whose basic inversion element is 90 180 c270 c (or more succinctly 123, hence the name). This provides very effective decoupling over a band- 

The ability to spin-lock magnetisation along a predefined axis plays an essential role in the TOCSY experiment, and Section 5.7.1 has already introduced the idea that a single continuous pulse or a series of closely spaced
