| 英文摘要 | The off-resonance effects on 2D NMR nutation of I = 3/2 quadrupolar nuclei are demonstrated with perturbation theory and numerical calculation in static samples. The off-resonant (Delta omega) rf field (omega(1)) enlarges a nutation frequency and consequently increases the measurement range of nuclear quadrupolar interaction parameters. When omega(e) > omega(Q)(max), and arctg(omega(1)/Delta omega)= +/-54.7 degrees (magic angle), the satellite lines (produced by coherence transfers) in a nutation spectrum are superimposed with the line of central transition, and hence the nutation spectrum is simplified and its sensitivity is enhanced. The nuclear quadrupolar interaction parameters of Na-23 nuclei in Na Omega molecular sieve are obtained using 2D NMR nutation. |
