Notes:
Doppler limited infrared laser spectra of H2 and D2 have been recorded in an ac discharge with diode laser sources and assigned to Δv=0 and ±1 sequence bands of the a–c system. Intense absorption signals from atomic hydrogen were also detected and used to confirm that some molecular spectra occurred in stimulated emission; as was found for a known D2 laser transition. Several of the diode spectra recorded at shorter wavelengths (Δv=1 sequences) cover regions previously observed by FTIR emission experiments on the a–c system. Both fine and hyperfine structure are revealed by the present studies and a preliminary analysis shows that while the a 3Σ+g state has negligible fine structure (at this resolution), hyperfine effects are apparent and are modeled using a bβS coupling case.
