  1. CH437 Heteronucleus NMR 담당교수 이석근

  2. Formamide의 500.23 MHz 양성자(1H) NMR Spectrum. (* 표시는 13C 위성 피크이고, # 표시는 15N 위성 피크임.)

  3. a b • 50.68 MHz에서 얻은 90% formamide 용액의15N NMR Spectrums. • 양성자와 커플링 된 스펙트럼(32 scan) • 디커플링하였지만, NOE가 없게 얻은 인버스-게이티드 스펙트럼(1 scan) • NOE가 조금만 나타나게 한 스펙트럼(1 scan) • 최대의 NOE가 나타나게 한 스펙트럼(1 scan) • Inept 스펙트럼(4 scan) c d e

  4. 121 MHz 31P NMR

  5. Oxygen(17O) NMR acetone

  6. Deuterium(2H) NMR

  7. Sodium(23Na) NMR 79.39 MHz 50 ppm Na +Dy(TTHA)

  8. 139La-NMR TTHA-La DTPA-La EDTA-La La(H20)63+

  9. 24.5 MHz 89Y NMR spectra of 0.1 M solution of a) Y(aq)+3, b) YEDTA(1), c) YDTPA(2), d) YTTHA(3). Line broadening was done by Lorentz multiplication (LB = 1 Hz) of the FID prior to Fourier transformation and base line correction was done by 5 degree of polynorminal function.
