Default Odd distortion in HOD peak in 1D DOSY (stebpgp1s)

Odd distortion in HOD peak in 1D DOSY (stebpgp1s)

I have a small distortion in the HOD peak in my 1D DOSY spectra. However, it only occurs for the HOD signal and no other peaks in the spectrum. Occasionally, I am able to "fix" this by not spinning the sample (though not always). Any help would be appreciated.

Peak height versus peak volume
Given a standard NOESY-based protein structure determination: Does anyone have any information on the benefits of measuring peak intensity by a volume integration method rather than simply measuring the peak height. Obviously integration is theoretically more accurate, but does it make any difference to the quality of the structures produced? especially if peak lineshapes are comparable? I was hoping to find some study comparing structures produced by both methods..... I'm also curious about the benefits of distance-calbrating NOEs to a curve rather than simply putting restraints...

[Question from NMRWiki Q&A forum] How many peaks should be in DOSY spectrum of D2O sample?
How many peaks should be in DOSY spectrum of D2O sample? Hello, I've recorded a DOSY data set and processed with Bayesian DOSY transform. There seem to be at least two peaks in the processed spectrum. Is the second one an artifact? In theory there might be a signal of H2O along with HDO, but wouldn't exchange of deuterium be much faster than the experiment time scale? Thanks.

[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...

[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...
