Abstract
The absorption coefficients of the collision induced spectrum of the interaction H2-He at 300 K between 200 and 700 cm-1 are presented. A lack of absorption (dip) due to the intercollisional interference effect is clearly seen at the frequency of the pure rotation line S1 of the free molecule of H2.
Résumé
On présente les coefficients d'absorption du spectre correspondant à l'interaction H2-He à 300 K entre 200 et 700 cm-1. Un défaut d'absorption ou « dip » caractéristique des effets d'interférences collisionnelles est clairement visible à la fréquence de la raie rotationnelle S1 de la molécule libre H2.
