1. Would you expect phosphorus to exhibit an NMR spectrum? Why or why not
2. When radio-frequency energy is absorbed by a nucleus with a spin of 1/2 that is in a magnetic field, what happens
3. How does the irradiation of nuclei in FT-NMR instruments differ from irradiation in other types of NMR instruments? What are the advantages of FT-NMR over the other NMR techniques
4. In many respects, the spectrum of CH3CH2I (iodoethane) appears to be identical to that of ethanol. What are the differences in the two spectra and why do these differences arise
