Representations of the two spin states of the proton interacting with a magnetic field The molecular structure of bromoethane

The expected NMR spectrum for bromoethane

The spin of proton Hycan by "up" or "down"

The spins for protons Hy can be "up", can be opposed (in 2 ways) or can both be "down"

The spins for the protons Hy can by arranged as shown in (a) leading to four different magnetic environments
