Why Is DOSY So Different From COSY?
During the 80th session of the Global NMR Discussion Meetings held on February 13th, 2024 via Zoom, Prof. Gareth Morris from the University of Manchester, United Kingdom, gave a talk on the topic "Why is DOSY so different from COSY?". The recording serves as a tutorial.
Abstract:
Peaks in COSY, NOESY, ROESY and HSQC 2D spectra either appear where they should, or not at all. In DOSY spectra, it is all too common to see peaks at incorrect positions in the diffusion domain. This tutorial will explore why this happens, what we can do about it, and how to avoid being misled by DOSY spectra.
