Binary And Ternary Mixtures

The infrared spectra of chloral, carbon tetrachloride, and chloroform have been determined between 1500 and 650 cm.−1 over a range of pressures in the gas phase. Absorption bands suitable for the quantitative analysis of binary and ternary mixtures of the components have been selected and their peak intensities shown to obey Beer's Law over the range of pressures studied. Ternary mixtures have been analyzed from the spectra with an accuracy of about 20%.The spectra of dichloromethane and methyl chloride have also been measured under comparable conditions.

Covalent Interactions

Two C–H⋯Cl–C and one C–H⋯F–C bonds stabilize (by 5.9 kJ mol−1) the dimer of chlorofluoromethane observed by rotational spectroscopy in the gas phase. The spectral analysis is complicated by the quadrupolar effects of the two nonequivalent Cl nuclei.
