Abstract
Infrared spectra of 1,1,2,2‐tetrachloroethane have been measured in the gaseous, liquid, and solid states and in solutions.Raman spectra of the same substance have been observed in the liquid and solid states. From the experimental results the equilibrium molecular forms of the rotational isomers have been determined. The normal vibrations of the molecule in the trans‐ and gauche‐forms have been calculated as an 8‐body problem, and the assignment of the observed infrared and Raman frequencies in all the states of aggregation has been made.Keywords
