Abstract
The vibrational structures of three paracyclophanes were investigated, ortho-dihydroxy-[2.2]paracyclophane (o-DHPC), mono-hydroxy[2.2]paracyclophane (MHPC) and 2,11-dithia[3.3]paracyclophane (2SPC). Gas-phase infrared spectroscopy helps to identify the most stable isomer of o-DHPC and MHPC in the gas phase, while FT-Raman spectroscopy was used to study S2PC. For o-DHPC the IR spectrum confirms that the EZ-rotamer dominates, while for MHPC the spectra agree better with the Z-rotamer, but are not unambiguous. The Raman spectrum of 2SPC showed a dominance of the trans isomer in the solid state.
