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 ...

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 ...

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 ...
