Abstract
IN a previous communication1, the rotational constants determined for the ground and excited states of the columbium oxide molecule have been reported as derived from the rotational analysis of the three bands λ 4,510 (1,0), λ 4,689 (0,0) and λ 4,915 (0,1). Due to an error, which has unfortunately crept in, in the calculation of the r
e values, it has since been found necessary to revise the analysis and to redetermine the constants. This work has been carried out. The two R and the two P branches and the K-numbering have been confirmed from the combination relationships. The revised rotational constants are:
