Hexacyclinol - NMR spectra vs plain images
I’m sure that many of you are aware of the infamous controversy over the total synthesis of Hexacyclinol . There are a plethora of arguments, from the purely synthetic chemical point of view to the spectroscopist perspective, which both put in doubt the veracity of aforementioned total synthesis. You can find, at the end of this post, a list of references that may be of interest on this subject. In this particular post, I would like to comment on several interesting aspects from an NMR standpoint.
In the original article’s “supporting...

[Question from NMRWiki Q&A forum] Correct mathematical formulas of the important window functions
Correct mathematical formulas of the important window functions
Hi,
regarding my C++/Qt NMR processing application (see http://qa.nmrwiki.org/question/149/problem-reading-and-transforming-vendor-data-using-cqt or http://cutenmr.sourceforge.net/) I have a question concerning the window functions.
I did research in the literature but could not find the "correct" mathematical formulas of the important window functions (exponential, gaussian, sine, sine squared, TRAF). For the gaussian function I found:
exp(-(t*LB)^2)
