Analyse rotationnelle et spectromètrique de la bande (2, 0) du système A2Π–X2Σ+ du radical CO+: Dédoublement Λ de l'état 2Π

Abstract

A high resolution grating spectrometer and a hollow cathode lamp were used to study the (2,0) band of the.A²Π–X²Σ transitions of the ion CO⁺. High resolution measurements permit satisfactory separation of the doublet components and facilitate study of the intensities, so it is possible to evaluate the p and q constants for the Λ splitting of the ²Π state. Earl's formulae are obeyed with a precision of better than 5%.
