Abstract
As part of an investigation undertaken in this laboratory on the emission spectra of halogens and halogen derivatives of methane1, the emission spectrum of iodine is being studied. The spectrum is excited by a high-frequency as well as a transformer discharge in iodine vapour of pressure equivalent to the saturated vapour pressure of iodine at room temperature. A Steinheil 3-prism glass spectrograph and medium Hilger quartz and constant-deviation glass spectrographs have been used as resolving instruments. Super Panchro-press P 1200 and Process Regular B 20 Kodak plates were used.
