英文摘要The three-photon resonant ionization spectroscopy of H-2 B-1 Sigma(+)(u) - X-1 Sigma(+)(g) (12,0) and C-1 Pi(a), - X-1 Sigma(+)(g) (2,0) exhibits abnormal pressure effects. Some of them are observed for the first time Pressure-induced abnormal line shift, line broadening, line splitting and spectral intensity variations can he well explained by a chanism of reabsorption of the third harmonic generation in the medium. Approximate expressions considering the phase matching requirement yield lineshifts, -splitting and -intensities at different pressures in good agreement with the experimental results. Two similar spectra are detected by two tandem electrode pairs in a gas call which give experimental evidence for THG reabsorption mechanism. The failure to obtain ion signal from circularly polarised light also supports the ab The failure to obtain ion signal from mechanism.
