insensitive nuclei enhanced by polarization transfer

acronym: INEPT
https://doi.org/10.1351/goldbook.08368
Pulse sequence in nuclear magnetic resonance spectroscopy that involves the transfer of nuclear spin polarization from spins with large Boltzmann population differences to nuclear spins of interest with low Boltzmann population differences.
Notes:
  1. INEPT uses for the polarization transfer in contrast to nuclear Overhauser effect (NOE) which arises from dipolar cross-relaxation.
  2. INEPT is a building block for many heteronuclear NMR experiments.
