    The origin of the system of bands around 2482 A.U. observed in a mercury lamp has been given evidence as due to mercury molecular ion. Quantitative determination of the intensity variations as a function of pressure and current of the 2482 bands and other band of neutral molecules, shows marked difference between 2482 bands and other bands. All the differences can only be explained on the basis of an ionic origin of the 2482 bands. The excited state of the molecular ion that emits 2482 bands is given evidence...

    The origin of the system of bands around 2482 A.U. observed in a mercury lamp has been given evidence as due to mercury molecular ion. Quantitative determination of the intensity variations as a function of pressure and current of the 2482 bands and other band of neutral molecules, shows marked difference between 2482 bands and other bands. All the differences can only be explained on the basis of an ionic origin of the 2482 bands. The excited state of the molecular ion that emits 2482 bands is given evidence as that state resulted from a combination of a normal atomic ion and a neutral atom at the 3P1 excited state.

    An analysis of the existing data for doubly ionized calcium in the extreme Schumann region below 1010 was made, and practically all the bright lines in this region were classified. 16 new terms were tabulated.
