Selective IR-induced isomerization of 1,2-dichloropropane isolated in xenon matrix

The conformations of monomeric 1,2-dichloropropane isolated in low temperature xenon matrix were characterized experimentally using FTIR spectroscopy. The interpretation of the experimental spectra was aided by ab initio MP2/6-311++G(3df,3pd) calculations. Relative energies of three structures, differing by the orientation of the Cl-C-C-Cl dihedral angle, fall within 0-6 kJ mol-1 range. The spectral signatures ...
