Book Description
Excerpt from Wave-Length Measurements in the Arc and Spark Spectra of Zirconium The majority of the wave lengths of Table 1 represent the means of from 3 to 11 determinations. The majority of those of Table 2 are based on 2 to 4 determinations. Lines of impurities in the zirconium have been omitted in all cases where their chemical origins have been established with certainty. Although the samples of metallic zir conium represented chemical purity approximating or surpassing 99 per cent, yet all contained as impurities the elements Fe, Ti, and Cr, and in two of them were detected traces of Al, Mn, and Si. Of course, the prominent lines of the recently discovered hafnium were also present, and with a few exceptions these, too, so far as their identity has been established, have been omitted from the following wave-length lists. The comparison of the Zr wave lengths with the infra-red Hf spectrum is based on recent unpublished observations by Meggers at the Bureau of Standards.

Book Description
Excerpt from The Structure of the Arc Spectrum of Zirconium When we resumed our work on the Zr spectra we had acquired from Dr. A. S. King, of the Mount Wilson Observatory, a set of plates copied from his furnace spectra of Zr, supplemented later with an advance copy of the temperature classifications of the Zr lines made by him and Miss Carter. 6 And from the late Prof. B. E. Moore, of the Brace Laboratory, University of Nebraska, we had obtained the films on which he had recorded the Zeeman effect of Zr out to 7, 000 A in the red. with these aids we were able to identify most of the stronger lines of Zr I as members of the quintet and triplet systems.
