Weitere Untersuchungen über die Isomerie der Benzildioxime. 24 S. In: Nachrichten von der Königlichen Gesellschaft der Wissenschaften... zu Göttingen. No. 1.
(Göttingen, Dieterich), 1889. - (25 x 17,5 cm). 24 S. Rückenbroschur, unaufgeschnitten.
Erste Ausgabe. - Aufgrund stereochemischer Annahmen erklären die beiden Wissenschaftler die am Benzildioxim gefundenen Isomerien. "In 1888 Auwers and Meyer substituted the name 'stereochemistry' for van’t Hoff’s 'chemistry in space.' At this time the concept of geometrical isomerism had not been extended to structures other than those involving carbon atoms. Auwers and Meyer found that there were three isomeric forms of benzildioxime and proposed, contrary to van't Hoff's principle of the free rotation of single bonds, that the isomerism resulted from the restricted rotation about the singly bound carbon atoms. Arthur Hantzsch and Alfred Werner elaborated the presently accepted theory in 1890 by extending geometric isomerism from doublebonded carbon atoms to double-bonded carbon and nitrogen atoms. Auwers and Meyer themselves aided in the confirmation of the Hantzsch and Werner theory" (DSB). - Erstes Blatt etwas angestaubt und mit kleinen Einrissen am rechten Rand, sonst gut erhalten. - DSB 1, 340
