NEW BOOKS industrial laboratory materials. There are more than 2000 new entries and a new section on air, water, and radiation pollution. Infra-Red Radiation. A. Vasko. 448 pages. The Chemical Rubber Co., 18901 Cranwood Parkway, Cleve­ land. Ohio 44138. $10.75 This reference is divided into two parts. Part I presents the laws of radi­ ation, descriptions of infrared sources, explanations of detectors, and the opti­ cal properties of numerous infrared ma­ terials. Part II reviews applications such as spectroscopy, pyrometry, medi­ cal, heat sources, etc. Microwave Study of Chemical Struc­ tures and Reactions. Peter Hedvig, Georgina Zentai. Translated into English. 4®% pages. The Chemical Rubber Co., 18901 Cranwood Park­ way, Cleveland, Ohio 44138. 1968. $16 This book is a translation of the work of the two Hungarian scientists, Peter Hedvig and Georgina Zentai. It deals with microwave rotational-inversion, electron spin resonance, nuclear mag­

netic resonance, and nuclear quadrupole resonance. Dielectric spectroscopy and electrical conductivity in solids are also covered. Theoretical and practical as­ pects of these subjects are considered.

U. S. Government Publications The following publications are avail­ able from the Clearinghouse for Federal Scientific and Technical Information, Springfield, Va. S2151. Prices are S3 each for paper copies and 65 cents for microfiche unless otherwise noted. Investigation of Crystal Imperfec­ tions by Means of Laser Light Scattering. AD-666 918. R. C. Powell, Air Force Cambridge Re­ search Labs., Bedford, Mass. 66 pages. Dec. 1967

This study includes the use of a unique apparatus having a laser light source for ultramicroscopy and angu­ lar scattering experiments. Investiga­ tions are done as a function of crystal growth direction, annealing, boule mor­ phology, polarization, chromium con­ centration, γ-irradiation, and tempera­ ture.

Measurement and Identification of Laboratory-Produced Vacuum Ul­ traviolet Spectral Lines. AD-667 584. N. V. Roth, R. C. Elton, Naval Research Lab., Washington, D. C. 41 pages. Feb. 1968

The publication describes the mea­ surement and identification of spectral lines of carbon, nitrogen, oxygen, and silicon on spectrograms obtained from a large theta-pinch plasma device. The technique includes the use of a computer program written in Fortran IV.

Instrumentation for Time-Resolved Mass Spectrometry. Application to Laser-Vaporization of Solid Ma­ terials. AD-669 453. K. A. Lincoln, U. S. Naval Radiological Defense Lab., San Francisco, Calif. 24 pages. March 1968

This report describes a technique for coupling a pulsed laser with a time-offlight mass spectrometer so that low vapor pressure materials, such as poly­ mers and refractories, can be vaporized directly into the ion source of the spec­ trometer.
