Fig. 2	Spin States	Creation of the B_e field by the circulation of electrons in response to the B_o field. B_e opposes B_o at the nucleus.
Fig. 3	Chemical Shift	Tetramethylsilane (TMS).
Fig. 4	Chemical Shift	NMR chart papers for ¹H and ¹³C NMR.
Fig. 5	Chemical Shift	The ¹H NMR spectrum of methyl acetate.
