Abstract
The bands of PrO at 8488.95 A and 7986.44 A of system I and at 7662.85 A of system III have been photographed on 6.6 meter concave grating spectrograph at a dispersion of 1.2 A/mm and their rotational structure analysed. They are assigned transitions fromv′ = 0 and 1 levels of A2 Δ5/2 andv′ = 0 level of B2 Δ5/2 to a commonv′’ = 0 level of the ground, X2 Π3/2 state.
