Infrared diode laser absorption spectra of portions of the 5{ital g}--4{ital f}, 6{ital h}--5{ital g}, and 8{ital i}--6{ital h} Rydberg bands of H{sub 2} and D{sub 2} have been measured at Doppler limited resolution in low pressure A. C. discharges. The spectra, arising from {ital L} uncoupled states of H{sub 2} and D{sub 2}, are assigned using an {ital ab} {ital 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) {ital V}{sub 6} model which became progressively better at higher {ital n} (and {ital L}). Results of multichannel calculations for a selected set of transitions are also reported.
