Lot description
Bohr, Niels, On the quantum theory of line-spectra. 3 Tle. in 1 Bd. Kopenhagen, B. Lunos 1918-22. Heftstreifen (OBrosch. zu den Tln. I & II eingebunden), in Schuber. 25,5 : 20,5 cm.

Erste Ausgabe der bahnbrechenden Abhandlung, in der Bohr das sogenannte Korrespondenzprinzip entwickelt, um bei großen Quantenzahlen den Übergang von der Quantenmechanik in die klassische Elektrodynamik zu beschreiben. "By 1918 Bohr had visualized, at least in outline, the whole theory of atomic phenomena .. He of course realized that he was still very far from a logically consistent framework wide enough to incorporate both the quantum postulates and those aspects of classical mechanics and electrodynamics that seemed to retain some validity. Nevertheless, he at once started writing up a synthetic exposition of his arguments .. in testing how well he could summarize what was known, he found occasion to check the soundness of his ideas and to improve their formulation .. - Bohr's theory of the periodic system of the elements, based essentially on the analysis of the evidence of the spectra, renewed the science of chemistry" (DSB). - Die zwischen 1918 und 1922 in drei Teilen publizierte Arbeit erschien in der Reihe Mémoires de l'Académie Royale des Sciences et des Lettres de Danemark , Section de Sciences, 8me série, Bd. IV/1, Fasz. 1-3.

DSB II, 247. - Rosenfeld 15. - Ekelöf II, 64.

First edition of Bohr's groundbreaking treatise on the "correspondence principle", which states that the behavior of systems described by the theory of quantum mechanics reproduces classical physics in the limit of large quantum numbers. 3 parts (all published) in 1 vol. Sewn booklet with bound-in orig. wrappers to part I and II, in modern slipcase.
