"A remarkable aspect of MRS has been the evolution of radio-frequency pulse sequences, "spin-gymnastics," invented to reveal ever more precisely the chemical, physiological and biochemical environment of hydrogen, carbon, phosphorous, nitrogen, fluorine, and other nuclei of interest to the biologist and physician," says Brian Ross, Director of Magnetic Resonance Spectroscopy, Huntington Medical Research Institutes, Pasadena, Calif.
Though similar experiments have been conducted in the past, they involved the use of radio-frequency pulses that are slower than laser-light pulses.
