Pulse sequences for high-resolution diffusion-ordered spectroscopy (HR-DOSY)

Characterization of Reactive Intermediates by Diffusion-Ordered NMR Spectroscopy: A Snapshot of the Reaction of 13CO2 with [Cp2Zr(Cl)H]

“…All spectra were acquired with a 5 mm TBI probehead. For the DOSY experiments the BPPLED [3,15] pulse sequence or a modification of the INEPT ± DOSY sequence were used. [8] The pulse-field gradients (g) were incremented in 32 steps from 2 % up to 95 % of the maximum gradient strength in a linear ramp.…”

Study of the BPP7a peptide and its β-cyclodextrin complex: physicochemical characterization and complete sequence specific NMR assignments

“…42 Two-dimensional inverse hydrogen-detected heteronuclear shift correlation spectra were obtained using a All DOSY experiments were performed using the stimulated echo with bipolar gradient pulse pair sequence, modified with an introduction of a presaturation pulse for solvent signal suppression (STEBPGP1S). 43,44 The duration of the magnetic field pulse gradients (δ) and the diffusion times (∆) were optimized for each sample in order to obtain complete dephasing of the signals with the maximum gradient strength. A series of 16 STEBPGP1S spectra on 16 K data points were collected in each NMR experiment, and the values of δ and ∆ were 3 and 33 ms, respectively.…”

Matrix-assisted diffusion-ordered spectroscopy

“…While there have been many advances in the design of diffusion NMR pulse sequences, they all share a number of common features 2,3 . A series of r.f.…”
