摘要: Line coupling induced by collisions leads to drastic modifications of the spectral profile 0003–0000 CO2 pressurized helium. Calculation these have been performed using two recent energy corrected sudden (ECS) formalisms. The formulations lead theoretical predictions rather similar and in good agreement with available data over extended ranges frequency perturber pressure. It has shown that a simultaneous fit pressure broadened linewidths near wing allows more accurate determination basic ECS parameters. For purpose, it necessary extend measurement widths high J values (up J≊90).
