1H-NMR Studies on Organolithiums and Development of New NOE Methods Neue, auf dem nuklearen Overhauser Effekt (NOE) basierende NMR-Methoden erlauben detaillierte Einsichten in die Lösungsstruktur von Lithiumorganylen und verwandten Verbindungen. "Rotating frame"-Methoden sind frei vom "Nulldurchgangsproblem" des NOE. Die Anwendung auf einen bekannten endo-Komplex zwischen tert-Butylamin und einem Calixaren deckte einen Literaturirrtum auf: es liegt ein exo-Komplex vor. Mittels einer Pulssequenz, die auf "Excitation Sculpting" beruht, konnte die Struktur einer chiralen Organolithiumverbindung aufgeklärt und in Zusammenhang mit der Stereoselktivität gebracht werden.
