Infrared laser spectroscopy of H2 and D2 Rydberg states. II. Diode laser spectra and assignment of 5 g –4 f , 6 h –5 g , and 8 i –6 h systems

Infrared diode laser absorption spectra of portions of the 5g–4f, 6h–5g, and 8i–6h Rydberg bands of H2 and D2 have been measured at Doppler limited resolution in low pressure A. C. discharges. The spectra, arising from L uncoupled states of H2 and D2, are assigned using an ab initio polarization mod...

Description
Summary:Infrared diode laser absorption spectra of portions of the 5g–4f, 6h–5g, and 8i–6h Rydberg bands of H2 and D2 have been measured at Doppler limited resolution in low pressure A. C. discharges. The spectra, arising from L uncoupled states of H2 and D2, are assigned using an ab initio polarization model supported by intensity calculations. Details of the different implementations of this polarization model are given in the preceding paper. The most useful was the single channel vibrationally extended (1)/(2)  V6 model which became progressively better at higher n (and L). Results of multichannel calculations for a selected set of transitions are also reported.
