Summary

An attempt to the automated structure elucidation of organic compound was made chiefly by use of NMR as follows: Partial structures which are suitable to construct a molecular structure are selected beforehand. Spectral information afforded by the computer tied into NMR spectrometer designates the number and kind of the partial structures. Then structure building up program constructs the molecular structure(s) based on these designated partial structures and molecular formula.

In 24 known compounds examined by this method, one correct structure was given for 9 compounds, and multiple number of answers including an appropriate structure were given for 15 compounds.

Zusammenfassung

Ein Versuch zur automatischen Strukturaufklärung organischer Verbindungen durch kernmagnetische Resonanz wurde in folgender Weise unternommen: Zunächst wurden Teilstrukturen ausgewählt, die sich zum Aufbau einer Molekülstruktur eignen. Ein an das Kernresonanzspektrometer angeschlossener Computer liefert die Information über Art und Anzahl der Teilstrukturen. Auf der Grundlage dieser Teilstrukturen und der Molekülformel liefert ein Struktur-Aufbauprogramm die Molekülstruktur. Für 24 nach diesem Verfahren geprüfte, bekannte Verbindungen wurde in 9 Fällen ein eindeutig korrektes Ergebnis erhalten; in 15 Fällen lieferte der Computer mehrere Antworten, darunter auch die jeweils richtige.
