Gaussian pulse cascades: new analytical functions for rectangular selective inversion and in-phase excitation in NMR

New radio-frequency pulse envelopes are presented for selective inversion and in-phase excitation in NMR. The envelope functions consist of superpositions of three or four time-shifted Gaussians with optimized widths and peak amplitudes. The offset dependence closely approaches ideal rectangular functions, as verified by simulation and expt. [on SciFinder (R)]
