Abstract

The emission spectrum of mercury hydride has been photographed in the second and third orders of a 21-ft concave grating in the region 2930–4550 Å. The light source was an electrodeless discharge tube containing a drop of mercury in an atmosphere of hydrogen and argon. Twenty-six bands of the A-X system and four bands of the B-X system have been analyzed, most of them to their predissociation limits. A table of these bands and a vibrational energy-level diagram are given. The behavior of the lambda-type doubling in the ²Π state for which the electronic coupling is Hund’s case a is compared with the theoretical prediction.
