| Abstract: | The concentration-dependent isotopic resolved structure of the 409 cm−1 Raman band of C6H5CCl3 prompts a vibrational spectra study of this compound. The gathering of spectroscopic vibrational data suggests the existence of two important effects, the intramolecular conformational effects and the intermolecular interactions. In particular, it is concluded that the occurrence of two symmetrical conformations whose relative abundance is dependent on the concentration of the sample can well interpret the peculiar features exhibited by the CCl3 stretching band at ca. 409 cm−1. |
