RESONANCE CARS IN BR2 MOLECULES AND BR-ATOMS
MetadataShow full item record
Resonance-enhanced CARS processes were studied in molecular bromine. On the basis of the known spectroscopic constants of the two electronic states involved, the features in the spectra could be identified. CARS signals from Br-atoms produced from dissociation of Br2 were obtained by tuning (omega-1 - omega-2) in resonance with the 2P1/2 - 2P3/2 spin-orbit splitting (3685 cm-1). Different hyperfine components were resolved in the spectrum.
