Abstract

The experimental investigation and theoretical analysis of the anomalies observed earlier in the rotational structure of the H2 Fulcher-α band system is carried out. The anomaly consists in the substantial deviation between the measured intensity ratios ofR andP lines starting from the same rotational level and the values predicted by the Hönl-London formulas. For the first time the quantitative interpretation of this phenomenon is given on the basis of the nonadiabatic theory of the perturbation of the rotational levels of the upperd 3Π + u state by the other3 Σ′ + u electronic-vibrational states of the molecule. The influence of the vibration-rotation interaction is also discussed and taken into account.
