Ground‐State Molecular Constants of Hydrogen Telluride

Abstract
The ground states of the five isotopic species H2130Te, H2128Te, H2126Te, H2125Te, and H2124Te have been analyzed by simultaneous least‐squares fits of ground‐state combination differences formed from the four bands ν1 + ν2 , ν2 + ν3 , 1 , and ν1 + ν3 . Values have been obtained for the ground‐state constants A , B , C , the four centrifugal distortion taus, and the empirical term HK added to the second‐order Hamiltonian, for each of these species.
