heteronuclear decoupling

synonym: decoupling
https://doi.org/10.1351/goldbook.08351
Spin decoupling in nuclear magnetic resonance spectroscopy between two different nuclei (e.g., \(\ce{^{13}C}\) and \(\ce{^{1}H}\)) by appropriate excitation of the decoupled nucleus.
Notes:
  1. Heteronuclear decoupling is normally performed to simplify spectra or to enhance signal-to-noise ratio by combining individual components of the NMR signal.
  2. Notation: \(\ce{^{13}C\{^{1}H}\}\) denotes observation of \(\ce{^{13}C}\) nucleus with simultaneous decoupling of \(\ce{^{1}H}\) nuclei.
