Abstract
The use of selective RF excitation is discussed. A spectrally selective, large tip angle RF pulse is used to detect a weak signal from a first chemical species. A non-selective, small tip angle pulse is used in measuring a signal from a second chemical species in exchange with the first chemical species. The acquired resonance data provides maybe used to measure the ratio of the spectrally distinct species in exchange.
