Abstract
From a lead arc in a hydrogen atmosphere at four to five atmospheres pressure, a "many-lined" spectrum in the region 5000-7000A due to PbH has been produced. Practically all of the lines have been assigned to ten bands constituting a transition between an upper state of low stability and a stable ground state (, ). Strong interaction with other states is evidenced by a very large spin-doubling () in the lower state and in the upper state by an unorthodox variation of with , irregular spin doubling, a prominent failure of the Mecke rule and a sharp cut-off of levels at about volt above , .
