Improvements in the determination of the continuously-scanned Raman excitation profiles (REP's) are described. The continuous-scanning technique is applied to ozone excited in the first continuum (the Hartley band). The Rayleigh excitation profile, which is required for intensity calibration, is obtained simultaneously. A theoretical calculation for the ozone Rayleigh excitation profile is also provided for comparison. REP measurements of the vibrational features up to 6 quanta are determined in the wavelength range of 238--271 nm. These spectra show oscillatory structures that are qualitatively but unambiguously identified as the Raman counterparts of those in the absorption spectrum. The use of overlapping dye mixtures to cover most of the Hartley band is required. Difficulties encountered in patching together these first-generation spectra are discussed in detail.
