question 9

Which of the following is/are false? A. NMR stands for nuclear magnetic resonance. B. NMR measures the resonance frequency of the magnetic moments of nuclei that have spin, such as 'H, 13C, 15N and 31p. C. The H NMR spectrometer produces an applied field which causes the random spin states of the protons to become aligned as a- and B-spin states. D. The H NMR spectrometer applies a magnetic field to organic compound's nuclei that can be shielded by that compound's electrons. E. The H NMR spectrometer applies a magnetic field to an organic compound's nuclei that is inversely proportional to the operating frequency of the spectrometer.
