The absorption spectrum of atomic iodine has been investigated in the spectral range λ 2100 to 1400Å. The iodine was dissociated by heating to 1000°C. A hydrogen discharge tube or an iodine discharge tube was used as the source of illumination. The former source revealed clearly that λ 1830...
It is generally supposed that the intensity of any particular line in a band spectrum may be calculated from the Maxwell-Boltzmann law, assuming the gas to be in temperature equilibrium. From the results of this experimental work, it appears that under some conditions of excitation other factors...
Schrödinger's equation may be approximated to any desired accuracy by a difference equation over a lattice covering the region of integration. The solutions of this difference equation minimize a certain quadratic form (analogous to the energy integral ∫ ψ * H ψ ) subject to certain...
A new band system of SnO with origin at 36,803 cm - 1 has been observed in an arc at reduced pressures. The lower state of this system is identical with that of the known A and B systems. The upper state is new and has a vibrational frequency, ω e = 497.8 cm - 1 . The complexity of the isotope...
1. Description of a method ("method of the trochoid") of concentrating and focussing weak electron beams so that they form strong sharp lines on a photographic plate. 2. Displacement of the beam thus formed by an additional field, enabling the observer to recognize the sign of the charge and to...
The perfection of various crystals has been determined by using an x-ray double crystal spectrometer. The materials examined were quartz, Rochelle salt, fluorite, tourmaline, pyrites, barite, rocksalt, gypsum, and the metallic crystals aluminum, iron, nickel, tungsten, and permalloy (65 percent...
