Download or read book New Vacuum Ultraviolet Emission Continua in the Rare Gases written by Robert E. Huffman and published by . This book was released on 1961 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several new vacuum ultraviolet-emission continua recently observed in the spectra of the rare gases helium, argon, and xenon are discussed. These spectra were produced with a windowless light source operated as a repetitive condensed discharge and equipped with a differential pumping system to separate the high pressure (up to 800 mm Hg of helium) light source from the 2-m vacuum spectrograph (pressure 1/1000 mm Hg). In helium two continua were observed at pressures above 150 mm in addition to the weaker 600 to 950 angstroms continuum. The brightest extends from about 1050 to above 4000 angstroms and seems connected with greatly enhanced lines of He(II). The other continuum is the completely broadened principal series extending from 584 to about 510 angstroms and containing broadened principal series absorption lines. With argon in a flow system or xenon isolated with a LiF window, previously observed continua were extended from their resonance lines to beyond 3000 angstroms. Details of the experimental observations and possible explanations of these continua are presented. (Author).

This book was released on 1968 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of investigations of absorption and emission processes in gases important in upper atmosphere chemistry and physics by a wide variety of spectroscopic techniques are presented. The principle area studied is the vacuum ultraviolet at wavelength less than 3000 A using monochromators and spectrographs equipped with rare gas continua and hydrogen continua light sources. Sample cells suitable for work at 20K or between room temperature and 650K, gas chromatography apparatus for purifying samples, fluorescence apparatus to obtain the visible and ultraviolet emission spectra of gases excited by vacuum ultraviolet irradiation, an apparatus for flash photolysis studies, and data processing equipment are described. Experimental studies of the absorption spectrum of carbon suboxide, the fluorescence spectrum of the methoxyl radical, the flash photolysis of methyl nitrite and absorption and emission spectra of the products of a microwave discharge through sulfur dioxide are reported. Finally, theoretical calculations on the electronic structure of carbon dioxide and carbon suboxide are discussed. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: This report first gives a brief introduction and survey of the previous work on discrete structure in the ionization continua of atomic gases observed by absorption spectroscopy at photon energies less than about 20 ev (600 A). The discrete structure observed is generally due to autoionization. The spectra of metal vapors such as the alkali and alkaline earths, and of the rare gases, argon, krypton, and xenon will be discussed. After this introduction, recent measurements in this laboratory of the absorption coefficients (cross sections) of the rare gases argon, krypton, and xenon will be discussed. Measurements were obtained down to 600 A with a photoelectric scanning technique using a helium continuum background at a bandwidth of 0.5 A. This bandwidth was sufficient to resolve the earlier members of the intense, diffuse, asymmetrical absorption line series originally found by Beutler between the 2P3/2 ground state and the 2P1/2 excited state of the ion. These measurements will be discussed and compared with other recent theoretical and experimental investigations. Finally, a compilation of references to papers on autoionization spectra arranged according to element and complete up to January 1964 is included. (Author).
