ROTATION-VIBRATIONAL STATES OF D-3(+) COMPUTED USING HYPERSPHERICAL HARMONICS

An extensive collection is presented of ro vibrational term values for D-3(+) computed from the highly accurate RKJK potential surface. Band origins are given for energies below 10000 cm(-1). The analysis of th e rotational structure includes all vibrational states with up to thre efold vibrational excitation, and term values are given up to J = 8 fo r the states (upsilon(1), upsilon(2)) = (0, 0), (0, 1), (1, 0), (0, 2) , (1, 1) and (2, 0), up to J = 6 for the states (2, 1) and (3, 0) and up to J = 5 for the states (0, 3) and (1, 2). The results obtained her e are compared with the available experimentally observed transition e nergies. Of the 11 observed but so far unidentified transitions, two c ould now be assigned uniquely.
