Abstract

We report a new set of improved vibrational constants for ScO, YO and LaO and some additional figures for these species. The idea has been to fill the lack of sufficient and suitable constants needed to define the potential-well necessary in some calculations where they are the main limitation, as in Franck-Condon factors for instance. In order to do this, unreliable head measurements and little available band origins are ruled out, taking into account only resolved rotational structure, even if fragmentary. The accuracy of the constants is very much increased. Test of the potential-well is done reobtaininq known rotational constants, and for further consistency numerical calculation of centrifugal distortion constants is performed and comparison shows agreement with experimental data.
