Relativistic calculations of electronic states of TeH

Abstract

Relativistic configuration interaction calculations of five ω–ω states [3/2, 1/2, 1/2(II), 3/2(II), 5/2] of TeH are carried out. Comparison calculations of the 2Π and 4Π λ–s states are also carried out with the objective of understanding the effect of spin–orbit interaction on the electronic states of TeH. These calculations enable assignment of some of the experimentally observed spectra. The 1/2(II), 3/2(II), and 5/2 states exhibit interesting avoided crossings.
