Abstract

Abstract Orientation of proton spin systems relative to one another in polynuclear aromatics through the use of 1H homo‐nuclear nuclear Overhauser effects (NOE) detected by heteronuclear multiple quantum correlation (HMQC‐NOESY) at natural abundance is reported. The experiment was explored as a potential alternative for problems in which a solution cannot be obtained by more conventional methods. Optimization of the HMQC‐NOESY experiment is discussed.
