Abstract
This paper presents new data on the optical absorption spectra of evaporated films of KI, NaI, RbI, NaBr, and KBr in the region between 1700 A and 2500 A. The measurements were made at room temperature and —180°C. The absorption spectra of the iodides reveal hitherto unreported structure in the fundamental-band region of the salts.Keywords
