"Two Devices Facilitating Spectrometry in the Far Infrared."

8vo. 370-373 pp. Figs. Wrappers. Fine. Richard M. Badger, professor of chemistry emeritus at Caltech, who specialized in molecular spectroscopy with X rays and infrared radiation. He made pioneering studies on the modes of vibrations and spectral energies in small molecules. The so-called Badger's rule relating force and internuclear distance in diatomic molecules is based on his work from 1933. "A return to the work on the spectra of polyatomic molecules was evident in the second part of the year, which he spent at Professor Mecke's Institute in Bonn. Badger and Mecke, recognizing the inherent difficulties in obtaining sensitivity and high resolution in the middle and far infrared, turned to the measurement of the spectra of polyatomic molecules in their overtones and combination tones, which lie in the near infrared and visible region of the spectrum. Here there were two important advantages: the use of photo- graphic plates (which now could be sensitized for this region) permitting extended exposure times, and the high resolution obtainable with long-focus gratings".
