Croucha and Lynn F. Gladdena The presence of paramagnetic species has a well-known strong eﬀect on the NMR relaxation times of liquids. WebbParamagnetism is due to unpaired spins. Nucleon spins, the basis of NMR spectroscopy, have a small angular momentum compared with that of the larger electrons, and is normally ignored when considering the paramagnetism arising from electrons. Electron spins produce a large effect.
