Intensity Measurements in Emission on 29 Bands of the O₂ Schumann-Runge System

Relative integrated photoelectric intensity measurements have been made upon each of the ν' = 0, νdouble prime = 9-19; ν' = 1, νdouble prime = 8-12; 16-20; ν' = 2, νdouble prime = 7-9, 15, 16, 19-21, bands of the Schumann-Runge System. These measurements have been interpreted, with the aid of Franck-Condon factors q_{ν'νdouble prime} and r-centroids r_{ν' νdouble prime}, to determine the variation of electronic transition moment R_e(r) with internuclear separation r as R_e(r) = const. (1 - 1.1807r + 0.35047r²); 1.44(Å) < r < 1.76(Å)

A `smoothed' array of relative vibrational transition probabilities p_{ν'νdouble prime} = R_e²(r_{ν'νdouble prime})q_{ν'νdouble prime} and band oscillator strengths f_{ν'νdouble prime} have thereby been determined for all bands of the system between 2450 and 5000Å.
