Evaluation of adiabatic frequency-modulated schemes for broadband decoupling in isotropic liquids
Line broadening in high-resoln. NMR spectra caused by heteronuclear scalar coupling is described, and various adiabatic frequency-modulated decoupling schemes in high-resoln. NMR spectroscopy are compared. The CHRIP-95 decoupling scheme, which uses a linea ...
1996Divergent double chirp pulses for refocusing quadrupolar interactions
To excite and refocus single quantum coherences in a three-level system with a quadrupolar interaction, it is possible to use frequency-modulated pulses with two diverging frequency components that are swept simultaneously through the two single-quantum tr ...
1996Measurement of cross-relaxation between amide protons in 15N-enriched proteins with suppression of spin diffusion
A variant of two-dimensional nuclear Overhauser effect spectroscopy (NOESY) is described which allows one to observe cross-relaxation pathways between protons that have heteronuclear scalar couplings to nitrogen-15 or carbon-13 nuclei. In 15N-enriched prot ...
1996NMR of residual protons in partly deuterated anisotropic materials with phase-alternated decoupling of deuterium spins
A new method is presented for decoupling spins with S = 1 like D in anisotropic media while observing other spins such as residual protons in partly deuterated samples. The carrier frequency of a weak radiofrequency (RF) field is applied near the center of ...
1996Quantitative determination of cross-relaxation rates in NMR using selective pulses to inhibit spin diffusion
Overhauser effects and hence internuclear distances can be measured accurately with selective expts. designed to suppress spin diffusion. It is essential to consider effects of both transverse and longitudinal relaxation during selective radiofrequency pul ...
1996Adiabatic coherence transfer in magnetic resonance of homonuclear scalar-coupled systems
By analogy to heteronuclear systems, coherence can be transferred adiabatically in the rotating frame between two selected spins I and S belonging to a homonuclear network of scalar-coupled spins. In contrast to cross polarization with const. radiofrequenc ...
1995Determination of active scalar coupling constants by two-dimensional convolution of complementary cross-peak multiplets
Method for detg. the coupling const. between two spins using a suitably chosen pair of selective expts., soft-COSY on the one hand and pure in-pause correlation spectroscopy (PICST) on the other, is presented. In weakly coupled system, soft-COSY yields cro ...
1995NMR cross polarization by adiabatic passage through the Hartmann-Hahn condition (APHH)
Geoffrey Bodenhausen, Serge Hediger
The heteronuclear cross-polarization efficiency in the rotating frame can be improved by sweeping the radiofrequency amplitude adiabatically through the Hartmann-Hahn condition. The enhancement is particularly significant for strongly coupled IS spin syste ...
1994A method for exciting transverse magnetization in magnetic resonance
In a method for exciting transverse magnetization by irradiating a nuclear spin system subjected to a const. magnetic field with a frequency-modulated RF-pulse (chirp-pulse) and with a further frequency-modulated RF-pulse (further chirp-pulse) for refocusi ...

In high-resoln. NMR spectra of scalar coupled spins in isotropic phase, it is possible to convert single- into triple-quantum coherences and vice versa by irradiating simultaneously at the frequencies of 3 chem. shifts. A triple resonance condition can be ...
