Excerpt from The Arc Spectrum of Bromine and Its Structure
The program of spectroscopic research in progress at the Bureau of Standards for more than 15 years has had as one of its objects the exploration of the hitherto unknown red and infra-red regions of the spectra of the different elements as far as present photographic methods will permit. Work on the spectrum of bromine was started in January, 1922, on receipt from Prof. J. M. Eder, of Vienna, of several Geissler tubes containing Br at pressures of 10, 20, 30, and 45 mm Hg. The experiments with these tubes revealed a spectrum extending at least to 8272 A. The lines, however, were not sharp, owing to the fact that with the transformer then available the tubes could be operated only with highly condensed discharges.

Verkäuferbewertung 5 von 5 Sternen
Paperback. Zustand: New. Print on Demand. This book presents a detailed analysis of the arc spectrum of bromine, a chemical element with seven valence electrons. The author's exploration reveals a remarkable agreement between the observed structure of the spectrum and the theoretical predictions for atoms with such an electronic configuration. By carefully examining the wave emissions of bromine, the author identifies a series of energy levels and transitions that provide important insights into the atom's electronic structure. This research contributes to the understanding of atomic physics and the broader field of quantum mechanics, while also providing a valuable resource for scientists studying the properties and behavior of bromine. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. Bestandsnummer des Verkäufers 9780260967237_0
