The potential energy function for O2thinsp;X(3sum;minus;g) and the transition dipole moment of the Schumannndash;Runge band nearXhyphen;state dissociation

摘要

Emission spectra were analyzed for transitions of O2(Bthinsp;3sum;minus;u,vrsquo;rarr;Xthinsp;3sum;minus;g,vlsquo;) withvlsquo;as high as 35. TheXthinsp;3sum;minus;gpotential energy function,Vx(r), was determined nearly to the dissociation limit with an estimated accuracy of plusmn;50 cmminus;1.Vx(r) is compared to the highest levelabinitiocalculation available. The transition dipole moment function, mgr;(r), for the O2Schumannndash;Runge band is also extended almost to the dissociation limit. The O2molecule now provides one of the best testing grounds forabinitiotheories of dissociation and radiation.
