β¦ Synopsis
Raman spectra of TiBr4 and TiI4 in solutions were obtained using the excitation lines of a He-Ne and an ArC laser. The spectra of TiBra showed a pre-resonance effect with selective enhancement of the stretching vibrations for the shorter wwelength of excitation. A typical resonance Raman e:'fcct was observed for Tit4 by the 5145 and 4880 J, excitation lines, which lie close to the maximum of the first absorption band, giving an intense overtone progression of the totally symmetric mode vl.
