[Question from NMRWiki Q&A forum] Are there ways to explain magnetic-field dependent chemical shift?
Are there ways to explain magnetic-field dependent chemical shift?
Hi everyone,
I was wondering whether anyone could help me to explain why the chemical shifts in my proton and carbon NMR results do not exactly match with those reported in the literature?The solvent used in my experiment is exactly the same as the one used in the literature of reference (CD3OD), however the frequency applied in my experiment was 500MHz as opposed to 400MHz by the study i am comparing my results with.
For example, in my proton NMR spectra, my results are usually 0.08 to 0.26 ppm higher than that in...

[Question from NMRWiki Q&A forum] Vnmr: What to do when explib command does not work?
Vnmr: What to do when explib command does not work?
Hello, in one of accounts on our system explib command does not work but works fine in other accounts.
explib lists experiments loaded into the given user space and shows which are queued or running.
Is there something I can do on the file system - maybe fix/delete some file or record to make it work again?
Thanks.

As soon as I began experimenting with the DOSY toolbox I was surprised to discover an unexpected hole, which is just a novel proof of my old theory on NMR imprinting.
If your first spectrometer is a Varian, you will become a certain kind of spectroscopist and a certain kind of programmer. If your first instrument is a Bruker, you will become a different spectroscopist and a different programmer.
If a brukerist programmer had written this toolbox, he would have imported the frequency domain spectrum and started from there. Mathias Nilsson is instead a Varianist and he imports...
