Hi NMRwikiers, for measuring scalar couplings we use some HSQC pulse sequences modified for obtaining the coupling in F1-dimension as a splitting of doublets for CH2 groups. As high resolution is needed we use high folding in the acqusition, but as a result we obtain a lot of coupling artifacts in phenyl signals. We think that the use of adiabatic decoupling schemes should give a reasonably good spectrum of phenyls but I have no experience in adiabatic decoupling. Anyone can give me a hand for Bruker spectrometers?

Partial deuteration is a powerful tool to increase coherence life times and spectral resolution in proton solid-state NMR. The J coupling to deuterium needs, however, to be decoupled to maintain the good resolution in the (usually indirect)C dimension(s). We present a simple and reversible way to expand a commercial 1.3mm HCN MAS probe with...

Mathematical treatment of adiabatic fast passage pulses for the computation of nuclear spin relaxation rates in proteins with conformational exchange
Mathematical treatment of adiabatic fast passage pulses for the computation of nuclear spin relaxation rates in proteins with conformational exchange
Abstract Although originally designed for broadband inversion and decoupling in NMR spectroscopy, recent methodological developments have introduced adiabatic fast passage (AFP) pulses into the field of protein dynamics. AFP pulses employ a frequency sweep, and have not only superior inversion properties with respect to offset effects, but they are also easily implemented into a pulse sequence. As magnetization is dragged from the +z to...

Decoupling, what modultaion frequency to use ?
Hi all,
Perhaps a stupid question, but so far no one answered this one to me.
I want to find out what decoupler modulation frequency (dmf in Varian syntax) is needed to properly decouple observed couplings. Can anyone tell me ? I am looking for a practical answer.
I found a paper on decoupling, i.e. Shaka, A.J., Keeler, J. (1987): Progr. NMR Spectroscopy, 19, 47-129. Although this paper is formally correct, it is also very hard to read.
So let's make a practical example:
On an 800MHz machine, the carrier is on water (4.5 ppm), and there are imino protons resonating at 12-14 ppm....

[U. of Ottawa NMR Facility Blog] Deuterium Decoupling
Deuterium Decoupling
Bruker NMR spectrometers equipped with a 2H TX board and 2H amplifier can be setup to carry out 2H observation and decoupling experiments while still maintaining a 2H lock. Two channel systems can use the 2H transmitter for 2H, 1H, 2H and X measurements. In addition to these, a three channel system can be set up for X measurements. The first figure below shows the 13C and 13C spectra collected for a mixture of deuterated solvents using two channels of an AVANCE spectrometer. The second figure shows the 13C, 13C, 13C and 13C spectra for the standard 13C sensitivity...

2H decoupling in gNhsqc
hi, I had an insteresting problem with 2H decoupling on the Varian 600 machine for the gNhsqc experiment. I am doing locking and shimming without 2H decoupling. once you set dn3='H2' and submit the experiment, the lock level with drop to around half. and for the similar ghnca_P expriment, there is no such problem. the lock always stays the same level no matter decoupling on or off. Could anyone give me some suggestion? thanks.
