THE INTERPRETATION OF THE WULF ABSORPTION-BAND OF OZONE

Intensities and energies of the three lowest singlet-triplet transitions of the ozone molecule have been obtained by means of analytic response theory calculations based on multi-configuration wavefunctions. Contrary to the accepted interpretation of a (1)A(2)<--X(1)A(1) transition we find that the lowest electronic band in the ozone spectrum, the Wulf band, is due to a singlet-triplet (3)A(2)<--X(1)A(1) transition (oscillator strength 6 X 10(-7)). The calculations also explain the absence of observable absorption to the lowest a B-3(2) State because of negligible oscillator strength (8 X 10(-10)).
