(27 x 22 cm). 1445 S. Halblederband der Zeit. Erste Ausgabe. - "His major spectral work, 'Recherches sur la constitution des spectres.', published in 1890, mapped out Rydberg's total approach with remarkable clarity. He conceived of the spectrum of an element as composed of the superposition of three different types of series - one in which the lines were comparatively sharp, one in which the lines were more diffuse, and a third that he called principal series even though they consisted mostly of lines in the ultraviolet. The first lines were located in the visible spectrum and were usually the most intense. The members of each series might be single, double, triple, or of higher multiplicity. Any particular elementary spectrum might contain any number (even zero) of series of each of the basic types" (DSB). - Stempel auf Vorsatz. Papierbedingt gering gebräunt.

First edition of this significant work that lays out the empirical formulae governing the frequencies of atomic spectral lines, a precursor to Bohr's development of the quantum theory. A handsomely bound copy in excellent condition, and rare in commerce. Atomic spectra are lines that appear across the visible spectrum indicating the wavelengths of light emitted or absorbed when atoms are energised by photons. Each element produces a different series of lines, and these can be used to determine the chemical components of a substance on Earth, or even of a star or the atmosphere of a distant planet. Inspired by Mendeleev's periodic table, Johannes Rydberg (1854-1919) was convinced that the electromagnetic spectra emitted by atoms could provide insight into atomic structure and theory. 'Notwithstanding the imperfect spectroscopic tables then at his disposal, Rydberg discovered most of the important properties of series spectra, including the relation between corresponding series in the spectra of related elements, and foreshadowed discoveries which were made later, when experimental work has sufficiently advanced' (Nature obituary, January 24, 1920). Rydberg's work was justified and expanded by Bohr's development of the quantum model of atomic structure in 1913, and Bohr was able to use his own theory to derive Rydberg's results, providing confirmation of both. First edition, first impression; tall 4to, (30 x 22.5 cm); 4 engraved plates of which 3 are double-page and 1 is folding; title page and plates faintly toned, contents clean otherwise; recent burgundy quarter morocco, marbled boards, titles to spine gilt, very good condition; 155pp.…

Lund, Håkan Olssons Buckdruckerei, 1906. Lex8vo. Orig. printed wrappers. Some small nicks to edges of wrappers. 30 pp., 2 large folded tables (the periodic system). First edition of Rydberg's important revison of the periodic system. "Rydberg?s study of the periodic properties of the elements led him in 1897 to suggest that certain characteristics of the elements could be more simply organized by using an atomic number instead of the atomic weights. This atomic number was to be identified with the ordinal index of the element in the periodic table. In 1906 Rydberg stated for the first time (the paper offered) that 2, 8, and 18 (that is, 2n2, where n= 1,2,3) represented the number of elements in the early periods of the system. In 1913 he went further, correcting an earlier error about the number of rare earths from 36 to 32, thus allowing the n = 4 group to be included in the pattern." (DSB).…

(Paris, Gauthier-Villars), 1890. 4to. No wrappers. In: "Comptes Rendus Hebdomadaires des Séances de L'Academie des Sciences", Tome 110, No 8. Pp. (369-) 428. (Entire issue offered). Rydberg's paper: pp. 394-97. In this paper Rydberg announced his formula, later termed "Rydberg's Constant - the paper being a shortened version of the larger paper, published at the same time in Kungliga Vetenskaps Akademiens Handlinger with the title "Recherches sur la constitution des spectres d?émission des éléments chimiques" - in which he stated as a fundamental principle that "in the spectra of all the elements analyzed and so far thjere are series of rays whose wavelenghts or wave numbers are functions of consecutive integral numbers". The equation became an importent inspiration for the development of quantum theory and for the formulation of quantum states by Niels Bohr. Bohr?s view provided an immediate interpretation of the combination principle by identifying each Rydberg spectral term multiplied by hc (Planck?s constant times the speed of light) with the energy of an allowable stationary state of the atom. The difference between two such states equaled the energy in the light quantum emitted in the transition from a higher allowable atomic-energy state to a lower one."His major spectral work, "Recherches sur la constitution des spectres d?émission des éléments chimiques", published in 1890, mapped out Rydberg?s total approach with remarkable clarity. He conceived of the spectrum of an element as composed of the superposition of three different types of series - one in which the lines were comparatively sharp, one in which the lines were more diffuse, and a third that he called principal series even though they consisted mostly of lines in the ultraviolet.

Stockholm, P. A. Norstedt & Söner, 1885. 8vo. Uncut, unopened in the original printed wrappers. In "K. Scenska Vet.-Akad. Handlingar. Band 10. No. 2". Fine and clean. 31 pp, + 2 plates. First appearance of Rydberg's important paper on the periodic table in which he intruduced atomic numbers and made his famous conclusion: "The discovery of the periodic system have made it impossible to consider the chemical elements as simple and independent, and it has thus become a matter of great interest to searching explain the context between them. [.] And it would certainly confirm that the differences [between the atomic weights] periodically change, one must assume that the atomic weights themselves grow after a periodic law when it progresses in the system, and thus are to be regarded as periodic functions of their number. "Rydberg?s most significant scientific contributions were to spectroscopy: but his involvement with spectra had its origin in his interest in the periodic system of the elements, an interest that endured throughout his professional life. His earliest published papers in physics dealt with the periodic table. In the introduction to his major work on spectra (1890), he stated that he considered it only a part of a broader investigation, the goal of which was to achieve amore exact knowledge of the nature and constitution of the chemical and physical properties of the elements. He held that the effective force between atoms must be a periodic function of their atomic weights and that the periodic motions of the atoms, which presumably gave rise to the spectral lines and were dependment on the effective force, thus might be a fruitful study leading to a better knowledge of the mechanics, nature, and structure of atoms and molecules and to a deeper understanding of the periodic system of the other physical and chemical properties of the elements. In line with contemporary conceptions, Rydberg?s view was that each individual line spectrum was the product of a single fundamental system of vibrations." (DSB).…

Lund & Leipzig, Gleerup & Harrassowitz, 1913. 4to. In the original printed wrappers. With author's presentation inscription to top of front wrapper: "Från vännen forf." Fine and clean. 41 pp. First appearance of Rydberg's important paper in which continued his revision of the periodic system. Here he ascribed two hypothetical new elements which he called nebulium and coronium and came up with the formula 2p*2 (p integer) which Sommerfeld called "cabbalistic" in his book "Atombau und Spektrallinien".…
