Abstract

A re-analysis of the Huggins and Hartley bands in the ultraviolet absorption spectrum of O-3 is presented in which the structure in both bands is assigned to vibrational progressions in the symmetric stretching mode nu (1) and the bending mode nu (2) but not the asymmetric stretching mode nu (3). The present improved fit of a larger range of bands results in relatively large anharmonicity terms, whereas previous assignments have relied on the motion being largely harmonic in the upper state. From a consideration of the shape of single surface required to support both sets of vibrational data, it is concluded that the Huggins bands almost certainly terminate on the 2 (1)A(1) state rather than the 1 B-1(2) state.
