NMR of solids is very different from that ... Powder patterns approximating to the above are found for solids, like CaSO 4.H 2 O that contain approximately isolated spin pairs. For most purposes ...

While couplings contain invaluable data ... making it an essential technique for routine 1 H NMR spectra acquisition. This information has been sourced, reviewed and adapted from materials ...

d) The indirect spin-spin coupling is a magnetic interaction between at least two NMR nuclei which is transmitted by bonding electrons. This interaction (sometimes also called J coupling) is only ...
