The A^{2}Π X^{2}Σ ^{+} emission spectrum of zinc deuteride
Abstract
The A^{2}Π X^{2}Σ ^{+} emission of ZnD was studied at moderate and high resolution in the region 346505 nm. A detailed rotational analysis of 10 bands has been performed using the ^{2}Π formulas of Mulliken and Christy, with the Almy and Horsfall centrifugal distortion term. The principal molecular constants for the X^{2}Σ ^{+} state are (cm ^{1}): B_{e} = 3.3990, α_{e} = 0.0964, D_{e} = 1.16 × 10 ^{4}, β_{e} = 6.4 × 10 ^{6}, γ_{0} = 0.122, ω_{e} = 1141.54, ω_{e}x_{e} = 24.29, and, for the A^{2}Π state, T_{e} = 23 280.55, B_{e} = 3.7772, α_{e} = 0.0868, D_{e} = 1.14 × 10 ^{4}, A_{0} = 343.29, p_{0} = 0.149, q_{0} = 1.53 × 10 ^{3}, ω_{e} = 1361.49, and ω_{e}x_{e} = 20.69. RKR potential curves and A X FranckCondon factors were calculated. A comparison was made with the spectrum of ZnH and the isotopic splitting for ^{64}ZnD, ^{66}ZnD, and ^{68}ZnD is briefly discussed.
