In this Letter, we have recorded and analyzed new absorption spectra of ozone (215-2400 nm) at temperatures between 203 and 293 K. Two vibrational progressions have been identified in the visible part of the spectrum between 375 and 505 mn, leading to vibrational assignments, upper state's vibrational frequencies and anharmonic coupling constants, and to an estimation of the vertical electronic energy of the B-1(1) state, in overall agreement with recent theoretical predictions and with measurements of isotopic shifts at lower energies that were available in the literature.
