Distorted/antiphase signals when doing Dosy

Distorted/antiphase signals when doing Dosy

Hello,

I am running Dosy experiment using ledbpgp2s sequence. I am getting sort of signal distortions. I tried the solutions you have mentioned in your discussions. I couldn't execute the loopadj as it always says lock gain is too high. I try to change the lock gain manually but still it couldn't keep that value. Finally, i performed Dosy with out lock on. I did lock off,locnuc off and l12 = 0 and run the experiment again but the problem still persists. I tried with other wide bore spectrometer and I don't get the distortion. The problem remains only in the Cryoprobe standard bore spectrometer with icon nmr. I am not sure what to try out more ! Please input your thoughts.

Regards Uma

1H-15N HSQC, edited by a 1H inversion recovery and observed in the antiphase component (IR-HSQC-AP) Could someone explain the experimental theory/basis behind 1H-15N inversion recovery filtered HSQC experiment observed in antiphase (IR-HSQC-AP)? I am still learning basic NMR theory, but would like to know about this particular experiment, which was used to detect paramagnetically broadened backbone resonances. Thanks.

[Question from NMRWiki Q&A forum] DOSY deep signal distortions DOSY deep signal distortions Hi heveryone,I'm trying to run some DOSY experiments, but the resulting spectra are VERY distorted, and this is not just a problem of phase. The strange thing is that these distortions didn't appear as long as a few days ago...

[U. of Ottawa NMR Facility Blog] Weak Lock Signals and Distorted NMR Spectra Weak Lock Signals and Distorted NMR Spectra A good 2H lock signal with a high signal-to-noise ratio is a real advantage for maintaining a stable magnetic field for long data acquisitions and also for shimming the magnet using the lock signal. Sometimes, however it is desirable to run NMR spectra for samples with only a only a very small quantity of deuterated solvent and therefore a very weak lock signal. Such may be the case when one is monitoring a chemical reaction by removing aliquots and adding a drop or two of a deuterated solvent to help with magnet shimming using the 2H lock...	nmrlearner	News from NMR blogs	0	04-20-2012 09:33 PM

[Question from NMRWiki Q&A forum] How to fix the broad antiphase artifact after SOL function in nmrPipe? How to fix the broad antiphase artifact after SOL function in nmrPipe? Hi, we've tried to apply SOL function of nmrPipe to process a 3D 13C edited NOESY. and the result is a wide antiphase-looking peak on water resonance that strongly distorts the baseline. Would you have any idea what might be causing this? First image is a screenshot of data using SOL processing step and the second one was prepared without SOL.

[NMR software blog] Installing the DOSY toolbox on a Mac Installing the DOSY toolbox on a Mac The DOSY toolbox is an open source program written by Dr. Mathias Nilsson that runs on Windows, Linux, Mac and on any other platform covered by MATLAB. I am going to review it next week, while today I am giving a few practical tips that I prefer to leave out of the review, for the sake of readability and tidiness. I know that 14% of my readers have a Mac, and I have verified that the original installation instructions of the toolbox are inaccurate and unclear (for the average Mac user at least), so today I will simply explain how you can install the...	nmrlearner	News from NMR blogs	0	08-21-2010 06:29 PM
[NMR software blog] Qr-dosy QR-DOSY At the beginning of the month we saw that there are cases where the diffusion coefficients can be measured with the same mathematical tools used to measure relaxation. We have seen DOSY spectra of pure compounds where each signal decays as a pure exponential. Even a mixture can behave in the same way, if the signals don't overlap. In summary, calculating the diffusion coefficients is often easy. What I was curious to discover was: is it possible to recalculate the components of a mixture if the diffusion coeffients are known? From a pure mathematical point of view the answer was...	nmrlearner	News from NMR blogs	0	08-21-2010 06:29 PM
