The idea of quantisation of energy is confusing me. For example in IR, the bond will only absorb energy that is identical to the energy of the bonds
bending or stretching vibrations. Why is this and what does the bond do with that new energy?
Then NMR, the proton will only absorb the exact amount of energy required to jump to the higher energy spin state. Why is this? Why doesn't it absorb
some energy and make a partial jump towards the higher spin state? |
