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: - Heteronuclear decoupling is normally performed to simplify spectra or to enhance signal-to-noise ratio by combining individual components of the NMR signal.
- Notation: \(\ce{^{13}C\{^{1}H}\}\) denotes observation of \(\ce{^{13}C}\) nucleus with simultaneous decoupling of \(\ce{^{1}H}\) nuclei.
