MEASUREMENT OF CHEMICAL EQUILIBRIUM RATIO USING A MAGNETIC RESONANCE SPECTROSCOPY SYSTEM 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. 10 28 30 32 34 IG -42 12l AMP. 38 r- - ----- ----- --- - ~ ~ 46INTER. 44 14 CNRLMEM. --,48 PRINTER MONITOR INEFC 54 CONTROL INER 5 CIRCUIT M. 5618 ITER.
