Abstract

Assignment of all ^13^C chemical shifts of perezone (1) and some derivatives was possible using time averaged 25·15 MHz spectra with the aid of proton noise modulated and CW decoupling. Rapid interconversion of tautomeric forms of 2,5‐dihydroxy‐1,4‐benzoquinones is deduced from the ^13^C spectra.

In vivo NMR has focused on using "P and 'H to study metabolism in humans. Comparable "C NMR studies have not been undertaken, presumably, because of its insensitivity. We report herein that the natural abundance I3C signal from CI glycogen is observable. The ability to observe the signal opens new
