Selective double- and zero-quantum spectroscopy

Several novel methods are introduced that allow one to excite and observe. double- or zero-quantum coherences involving a selected pair of spins. All sequences described employ 270 Deg pulses with Gaussian envelopes, not only for selective excitation, but also for the conversion of single- into double- or zero-quantum coherences and vice versa. Illustrative NMR spectra of trans-2-phenylcyclopropanecarboxylic acid, obtained by using the methods, are presented. [on SciFinder (R)]
