Vibrationndash;Rotation Interaction Effects in Calculated Franckndash;Condon Factors. II. Hydrogen Lyman and Fulcher Bands

摘要

Calculated Franckndash;Condon factors, explicitly including previously neglected vibrationndash;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 theB1Sgr;uplus;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.
