HIGH-ACCURACY MEASUREMENT OF VIBRATIONAL RAMAN BANDS OF OZONE AT 266-NM 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.
