VIBRATION-ROTATION INTERACTION EFFECTS IN CALCULATED FRANCK-CONDON FACTORS .2. HYDROGEN LYMAN AND FULCHER BANDS

Calculated Franck-Condon factors, explicitly including previously neglected vibration-rotation interaction effects, are reported for 450 Lyman and 24 Fulcher bands of the hydrogen molecule. Large concellation effects, depending on rotational quantum number, are found for a number of Lyman bands. Where comparison is possible, the results show good qualitative agreement with experimentally determined intensity distributions. Using alternative representations of the B 1Su+ potential curve (upper state of the Lyman bands) it is shown that the calculated intensity distribution for some bands are highly sensitive to detailed features of the molecular potential curves.
