Hardcover. Etat : Very Good. ++This is a great classic, a foundation paper in the history of spectrum analysis.++ Kirchhoff, Gustav and Robert Wilhelm Bunsen. "Chemische Analyse durch Spectralbeobachtungen," in "Annalen der Physik und Chemie," Leipzig: Johann Ambrosius Barth, 1860, vol. 110, pp.161-189 in the full volume of viii, 660pp. [++] Offered in the entire volume, very sturdily bound in relatively recent black cloth, which has a library Dewey number on spine bottom. Provenance: Universitat Konstanz, with two rubber stamps and several pencil annotations on rear of the title page. Very light and very occasional foxing, here and there. Fresh and crisp copy. [++] "Kirchhoff s major contribution to physics was his experimental discovery and theoretical analysis in 1859 of a fundamental law of electromagnetic radiation: for all material bodies, the ratio of absorptive and emissive power for such radiation is a universal function of wavelength and temperature. Kirchhoff made this discovery in the course of investigating the optical spectra of chemical elements, by which, in collaboration with Bunsen, he laid the foundation of the method of spectral analysis (1860) [this paper].--Complete DSB, online, "Kirchhoff". [++] "(Bunsen and Kirchhoff) demonstrate the value of their spectroscope [invented the preceding year, 1859, with the results also published in the Annalen] by heating an ore, finding unknown spectral lines (in the blue region), and thereby discovering the metal cesium."--Parkinson, Breakthroughs, 1860 (Chemistry), pg 356. [++] In the 1860 s Bunsen and Kirchhoff worked together to develop the field of spectroscopy. Kirchhoff realized in 1859 that when colored flames of heated materials, which usually give bright, sharp emission spectra, are placed in the path of an intense light source, they absorb light of the same wavelength that they otherwise emit, and produce characteristic absorption spectra. Bunsen saw that analyses of absorption spectra could be made in order to determine the composition of celestial and terrestrial matter. He further predicted that spectral analysis could aid in the discovery of new elements that might exist in too small quantities or be too similar to known elements to be identifiable by traditional chemical techniques. Spectral analysis led to Bunsen and Kirchhoff s announcement in 1860 of a new alkali metal, cesium, detected in a few drops of the alkaline residue from an analysis of mineral water obtained from Durkheim. The element was named cesium (from the Latin caesius, sky blue ) because of its brilliant blue spectral lines."--Complete DSB, online (Bunsen).

(22,5 x 14,5 cm). SS. (89)-168.; SS. (329)-408und SS. (489)-560. Mit 3 lithographierten Tafeln, davon 1 gefaltete und zwei farbig. Moderner Halbleinwandband im Stil der Zeit mit 2 (von 3) beigebundenen Umschlägen. Erste englische Ausgabe dieser berühmten Gemeinschaftsarbeit, in der die beiden Wissenschaftler erkennen, "daß eine jede verdampfbare Substanz, in eine Flamme gebracht, oder jeder glühende Dampf ein charakteristisches Spektrum habe, und daß das Spektrum deshalb ein ausgezeichnetes Mittel für die chemische Analyse sei und begründen dadurch die Spektralanalyse" (Darmstaedter). Weiter beschreiben sie ihre Untersuchungen und die damit neu entdeckten Elemente Cäsium und Rubidium. - Vereinzelt gering stockfleckig. Das erste Blatt mit restauriertem Eckabriss. Die letzte Tafel mit zwei Fleckenrändern, sonst gut erhalten. - DSB 7, 379 und 2, 586; Darmstaedter 587, 595 und 607.

Leipzig: Johann Ambrosius Barth, 1860. 8vo. (207x124mm). Entire volume offered here in contemporary card board binding with hand written paper label to spine. A fine copy. First edition of the paper which marks the beginning of spectrum analysis. In this work Kirchhoff and Bunsen announced their discovery of the two alkali metals, cesium and rubidium, with the aid of the spectroscope they had invented the year before. These discoveries inaugurated a new era in the means used to find new elements.
