Abstract
Fourth-order many-body perturbation-theory calculations of the spectroscopic constants of are presented as an attempt to help identify possible astronomical or laboratory observations. The results for the rotational and vibrational constants are, respectively, 4.61 and 1511 . Similar calculations are made on , where comparison with experimental values shows excellent agreement, indicating reliable results for
