| Abstract: | Vibrational spectra are reported and assigned for the planar D3h symmetry cyclopropenium cations C3X3]+ (X= Cl, Br or I) from investigations of the compounds C3Cl3AlCl4, C3Cl3GaCl4, C3Cl3FeCl4, C3Cl3SbCl6, C3Br3AlBr4 and C3l4, using conventional infrared and Raman spectroscopy and Fourier transform Raman spectroscopy. The symmetric C—X stretching modes of C3X3]+ occur at 458, 269 and 180 cm?1 and the ring-breathing modes at 1790, 1732 and ca. 1650 cm?1 in C3Cl3]+, C3Br3]+ and C3I3]+, respectively. A normal coordinate calculation is performed for C3Cl3]+. |
