The Spectrum of CuO. Rotational Analysis of Some Blue and Violet Bands

Abstract
Four new band systems of the emission spectrum of CuO have been rotationally analyzed, namely the E 2Δ-X 2Π i , H 2Π-X 2Π i , I 2Π-X 2Π i and P 2Π-X 2Π i systems. Perturbations in the excited states are discussed. Molecular constants of the new states are given.
