Abstract

The 0-0 band of the A 3Πinv-X 3- system of ND was excited in an electrodeless microwave oscillator (2450 Mc./s.) discharge and photographed on a 6·6 meter concave grating spectrograph in the second order at a dispersion of 0·56 A/mm. Twenty-five out of the predicted twenty-seven branches have been identified in the rotational structure of the 0-0 band. From a rotational analysis, the following rotational constants have been determined: (i)X 3 ∑ - state- B0(cm.−1) D0(cm.−1) (2λ + ϒ) (cm.−1) 8.7757 4.68 × 10-4 −1.8356. (ii)A 3 ∏ inv state - B0(cm.−1) D0'(cm.-1) A(cm.-1) C0'(cm.-1) D2'(cm.−1) V00'(cm.−1) 8.7688 5.02 × 10-4 -31.89 -1.40 +0.0118 29799.5
