High-accuracy measurement of vibrational Raman bands of ozone at 266 and 270 nm excitations

Resonance Raman spectra of ozone at two excitation wavelengths (266 and 270 nm) have been measured up to 11 000 cm−1. Band origins have been measured to high accuracy and determined to within a few cm−1. Several bands beyond the dissociation limit have been observed. All prominent bands observed in this work fit to a two-oscillator Darling–Dennison model. An analytical two-dimensional potential energy surface has been constructed based on the new experimental data.
