A Recording Spectrograph for the Far Infra‐Red
(The American Institute of Physics, 1938-12)
This spectrograph records upon sheets of photographic paper 20×30 inches in size, spectra lying in the range between 18μ and 200μ. Of this range, 9μ may be spread over a single record, or as much as 100μ may be covered, ...
Qualitative and Quantitative Chemical Analysis by Line Emission Spectra
(The American Institute of Physics, 1939-11)
A METHOD FOR DETERMINING CRITICAL CONSTANTS AND ITS APPLICATION TO DIPHENYL (C6H5⋅C6H5)
(The American Institute of Physics, 1930-10)
A relatively simple method, leading to an evaluation of the critical constants characteristic of a substance as well as the liquid and saturated vapor densities with varying temperatures is described. The method is employed ...
Der Paschen-Back-Effekt der Hyperfeinstruktur
(Springer-Verlag, 1930-01)
Die Theorie des Paschen-Back-Effektes für gewöhnliche Multipletts wird erweitert zum Zwecke ihrer Anwendung auf Hyperfeinstrukturen, welche von einem Kernmoment herrühren. Die Ergebnisse werden mit den Backschen Aufnahmen ...
The Infrared Absorption Spectrum of Carbon Suboxide
(The American Institute of Physics, 1937-08)
The infrared absorption spectrum of carbon suboxide vapor has been studied under low dispersion in the region from 2μ to 25μ. The vibrational bands observed may be satisfactorily accounted for on the basis of a linear ...
