We have recorded high-resolution polarized and depolarized resonance Raman spectra of molecular iodine with excitation by argon-ion laser lines at 496.5, 488.0, and 476.5 nm up to the seventh, and with 457.9 nm up to the fifth, overtone. These spectra were also calculated numerically applying second-order perturbation theory. In contrast to earlier publications on this subject, special emphasis was put on obtaining highly reliable polarized and depolarized spectra. The variations of the spectral band shapes and depolarization ratios obtained at different excitation wavelengths could be explained by means of the specific contributions of the two excited electronic states [Formula: see text] and 1П1u. About 60 different experimentally obtained spectra were finally used to derive the positions of the two excited-state potentials involved in this type of light scattering. The derivation was done by comparison of the experimental and theoretically simulated spectra where parameters of the 1П1u as well as of the [Formula: see text] state potentials were varied. Key words: resonance Raman scattering, diatomic molecules, potentials, excited electronic states.

An analytical technique for aerosol samples which utilizes the resonance Raman effect is described. The aerosol particles were generated at 50 kHz by a vibrating orifice. The nominal particle size was 45 µm in diameter. The visible lines (4579, 4765, 4880, and 5145 Å) of a continuous argon-ion laser were used as the excitation source. Within the coverage of the laser wavelengths, effects of pre-resonance, resonance, and post-resonance Raman scattering were studied. Under the resonance condition, the enhancement of p-nitrosodimethylaniline is 5.5 × 104 when compared to that of nitrate ions. The corresponding concentration of detection limit is 10−6 molar.

Remote Analysis

Results of a laboratory study for the applicability of the resonance Raman effect for remote analysis of air pollutant molecules are presented. It was found that the influence of the absorption of the exciting laser light as well as of the scattered resonance Raman light by the scattering gas can reduce the observed resonance signal to normal Raman scattering levels. The laboratory detection limit for continuum resonance Raman scattering of iodine was found to be of the order of 30 ppb.
