In order to obtain information relating to the electronic structure of MnO, the visible system of this molecule has been photographed from an arc at a low pressure of oxygen. New bands have been observed. The rotational analysis of the 1–0 band has shown that this system comes from a A6Σ+–X6Σ+ transition, the lower state of which is the ground state of MnO. The rotational and spin–spin constants of the two states involved in the transition have been determined.
