The Modernized Metric System: the International System of Units (SI) and its Relationship to U.S. Customary Units
Chart of the six base units of the modernized metric system, including length, time, mass, temperature, electric current, and luminous intensity.
Standard X-ray Diffraction Powder Patterns: Section 6. Data for 60 Substances
Report documenting standard x-ray diffraction powder patterns for various compounds, intended to replace previous data or provide information for new substances. It describes the methods and, for each substance, outlines any previous data as well as information about the sample used and structural data, with a table of diffraction patterns.
Microwave Spectral Tables: Volume 4. Polyatomic Molecules Without Internal Rotation
From Introduction: "This volume contains data on the microwave spectra of 166 polyatomic molecules incapable of exhibiting internal rotation."
Microwave Spectral Tables: Volume 5. Spectral Line Listing
From Abstract: "This volume is a listing of the spectral lines reported in Volume I, III, and IV of the Microwave Spectral Tables. These lines are listed according to ascending magnitude of frequency and should provide a steady reference."
Investigation of the Exploding Wire Process as a Source for High Temperature Studies
From Introduction: "It is the purpose of this monograph to bring together and report the results of numerous exploding wire experiments performed at the National Bureau of Standards over the past five years."
Colorimetry
"The definition of color, as a characteristics of light, and the basic principles of its measurement are given. The reduction of spectrophotometric data to three chromaticity coordinates by means of the three-function CIE standard observer system for colorimetry is described. Various methods of direct colorimetry, and visual and photoelectric methods of colorimetry by differences from material standards are treated" (p. 1).
Nickel and Its Alloys
From Abstract: "This monograph reviews available information on the production, properties, and uses of high-purity and commercial forms of nickel, and on the properties and applications of its important alloys, both ferrous and non ferrous."
Technology of Liquid Helium
From Abstract: "This treatise is a source document containing information on helium resources, production, conservation, thermodynamic properties, liquefaction and refrigeration techniques, transportation and storage of liquid and safety requirements. It also contains a discussion of uses for liquid and cold gas in cryoelectronics, superconductivity, bubble chambers, cryopumping and missile and space systems."
Hydrogenation of Ethylene on Metallic Catalysts
Catalyzed hydrogenation in the presence of unsupported catalysts, especially of evaporated films of pure metals is discussed.
Saturated Liquid Densities of Oxygen, Nitrogen, Argon, and Parahydrogen
Integrated tables of pressure, volume, and temperature for the saturated liquid, from the triple point to the critical point, for oxygen, nitrogen, argon, and parahydrogen.
Oscillator Strengths and Transition Probabilities fro 3288 Lines of Fe I
Report of a homogeneous set of intensity-related data calculated for 3288 spectral lines of Fe I in the region from 2100 to 9900 angstroms. The quantities tabulated in the present monograph include log (g__), log (gf), gf,f,gA, and A. Since recent investigations do not support excitations corrections in the case of Fe I and certain other spectra, the present tabulation incorporates a removal of that normalization function. This recalculation affects the values for all lines whose upper energy levels lie above 46000 cm -1 and should significantly improve the internal consistency of the present data.
Infrared Spectroscopy of Carbohydrates: A Review of the Literature
Report presenting of survey of the literature on the infrared spectroscopy of carbohydrates in order to assemble and systematize information in this field. Discusses principles and instrumentation, sampling techniques, comparison of samples, and the interpretation of the spectra. In addition, examples are discussed of the use of infrared spectra for qualitative and quantitative purposes and in the determination of structure. Special techniques are briefly described.
Acid-Base Behavior in Aprotic Organica Solvents
Report presenting the National Bureau of Standards' research program designed to determine and explain acid-base behavior in aprotic organic solvents and to develop methods and reference materials for determining total acid and base content and relative strengths of acids and bases in the media.
Acceleration Due to Gravity at the National Bureau of Standards
Report describing the determination of the absolute value of the acceleration due to gravity at the National Bureau of Standards.
