Determination of Dunha m constan ts and potential en ergy curv es for InH from co mbined an alysis of UV/visible and infr ared spect ra

Spectroscopic investigations on InH began in ۱۹۳۸, and so far, several electronic transitions involving the x lat ground state and the low-lying excited states have been observed [۱-۴]. The a PII → X'st, a PII, X 'st and A 'II → X'st transitions appear near ۱۶۲۰۰, ۱۶۸۰۰ and ۲۲۰۰۰ cm-۱, respectively.Data analysis and results: We used the experimental data listed in Tables ۱ and ۲, and determined spectroscopic constants for the X 'st, a IIand a 'Il, states of InH by least-squares fitting. All the observed transition wavenumbers were fitted using the Dunham expression:
