Abstract

BANDS attributed to iodine oxide (IO) were observed by Vaidya1 in a flame of methyl iodide, and analysed into two systems, A and B. More recently, Blake and Iredale2 have published a revised analysis for system A ; when this formula was used to arrange the bands, an obviously unsatisfactory intensity distribution was obtained. We have re-measured the bands, and extended the system to longer wavelengths. It is now found that all the bands can be arranged into one system instead of two, this system being an extension of the B system, with modified values of ν". The bands are listed in the accompanying table ; intensities are visual estimates making some allowance for variations of plate sensitivity with wave-length.
