Criteria for the accuracy of composite pulses in multiple-quantum NMR

The correct use of composite pulses in multiple quantum NMR spectroscopy is described using the conventional sequence for 1-dimensional multiple-quantum filtration. The criteria for correct composite pulse selection which gives improvement in the NMR spectra are given. The effects of choosing the correct composite pulse were demonstrated for 2,3-dibromopropionic acid. The composite pulses of R. Tycko et al. (1985) are effective in compensating for pulse errors when applied to an arbitrary initial d. operator. [on SciFinder (R)]
