✦ Synopsis

The infrared spectra of liquid cis-and truns-1,2-diiodocyclopropane were measured from 4000 to 200 Em-'. Raman spectra between 4000 and 50 cm-' of the two compounds as liquids and of the solid cis isomer were also obtained. All of the 21 normal vibrations of the two molecules were convincingly assigned on the basis of Raman depolarization ratios and group frequency correlations. Comparisons are made with the normal modes of related compounds. There is excellent agreement with those assignments previously proposed for the two isomers of 1,2-dibromocyclopropane, cis-1,2-dichlorocyclopropane and related modes of iodocyclopropane.

The infrared and Raman spectra of cis-and trans-1,2-dibromocyclopropane have been measured in the liquid phase from 4000 to 50 cm-'. An assignment of all fundamentals of the two isomers is proposed which is in accord with all the well established assignments of simple bromocyclopropanes and disubsti
