BOHR, NIELS.

Über die Anwendung der Quantentheorie auf den Atombau. I. Die Grundpostulate der Quantentheorie.

Berlin, Springer, 1923. 8vo. In contemporary half cloth with gilt lettering. In "Zeitschrift für Physik" Bd. 13 & 14, 1923. Entire volumes offered, bound in one. Stamp to front free end paper, otherwise a fine and clean copy. Pp. 237-255. [Entire volume: V, (1) 426 pp.].

First edition. As Bohr in his 1918 paper (The quantum theory of line spectra) had discussed the expectation that there was a necessary connection between the classical and the future theory in the limit of large quantum numbers, and in a later paper (1920) named it "Korrespondenzprincip" (Principle of Correspondance), Bohr now in the paper offered discussed again the fundamental principles of Quantum Theory in connection with the Principle of Correspondence.
Rosenfeld No 29.

Also in the volume is Born & Heisenberg's paper, "Über Phasenbeziehungen bei den Bohrschen Modellen von Atomen und Molekeln", on Bohr's atomic model, being a part of Heisenberg's Habilitation, which he completed under Born in 1924 in Göttingen.
