Notizen:
A NOESY-type experiment with multiple mixing periods and acquisitions within a single pulse sequence was used to obtain a complete NOE correlation map of a small organic molecule. Incorporating multiple mixing periods and acquisitions into a single sequence can eliminate the need for repeating NOESY experiments with different mixing periods to observe dipolar exchange of considerably different rates or to determine exchange rates. The sequence has been applied to the molecular structure elucidation of cis-8a-vinyloctahydro-3H-2-benzopyran-3,7-dione, a small organic molecule where the use of a single mixing period does not reveal all protons undergoing dipolar exchange.
