A scientist investigates the possibility of neutron spin resonance, and has available a commercial NMR spectrometer operating at 300 MHz for 1H nuclei. What is the NMR frequency of the neutron in this spectrometer? What is the relative population difference at room temperature? Which is the lower energy spin state of the neutron?

13C NMR spectroscopy provides valuable information about the environments of a molecule's carbon atoms. Because carbon atoms are often connected to hydrogen atoms, which could split the carbon signal through spin-spin coupling, the coupling between C and H is often "turned off" through the use of broadband decoupling, causing each C signal to appear as a singlet.

What effect does increasing the operating frequency of a 1H NMR spectrum have on each value: (a) the chemical shift in δ; (b) the frequency of an absorption in Hz; (c) the magnitude of a coupling constant J in Hz?
