Abstract

The perpendicular v 3 fundamental band of the H 3 O + -ion has been remeasured with a colour centre laser. Improved results have been achieved by combining our experimental data with the recently published line positions of Begemann et al . and Bunker et al . For the first time the l -type doubling constant for the a-species has been determined, together with an additional l -type resonance parameter which describes the splitting of the ( Kl ) = -2 level.
