46. Which of the following statements about the 1H NMR (Nuclear Magnetic Resonance) experiment is incorrect? (A)The energy difference between the two spin states ( = +1/2 and =-1/2) depends on the strength of the magnetic field. (B)When energy absorption takes place, the electrons are excited by the electromagnetic radiation to obtain the NMR signal. (C) When aligned with the magnetic field, the energy of a proton with spin of mi = +1/2 is lower than that with mi = -1/2 when aligned against it. (D) The relative population of the upper spin state, Nupper, and of the lower spin state, Nlower, is given by the Boltzmann equation (Nupper / Nlower = e-△E/kT). (E) The energy needed to flip the spin of a proton is within the radio frequency range of the electromagnetic spectrum.

65. Which of the following statements about I D NMR and 2D NMR spectroscopy is INCORRECT? (A) ID NMR is faster than 2D NMR. (B) ID NMR gives less information than 2D NMR. (C) 2D NMR spectrum provides information about the spatial relationships between different nuclei in the sample, such as the distances and angles between atoms. (D) 2D NMR distinguishes between the overlapping signals that exist in larger molecules. (E) The advantage of 2D NMR spectroscopy is that it requires only one frequency axis.
