BalOgenOalkPnea exhibit intenae infra-red absorption banda In the region -1 1140-1330 cm , which can be of diagnostic value and should be included, along with the characterlatic C-halogen stretching fraquenciea, in spectral correlation tables.
Without exception, the standard texta on infra-red correlations of organic molecules include a statement, or Implication, to the effect that the only characteristic absorption in the infra-red spectra of halogenoalkanea la that aaaociated with the carban-halogen atretching mode.
1 Unfortunately, this is of little value for routine diagnoaia of bromo-and iodoalkanea

The i.r. spectra of trans-polyalkenamers both in the amorphous and in the crystalline state have been studied. The spectra of the amorphous polymers are interpreted on the basis of the known correlations of olefinic hydrocarbons. In the spectra of crystalline polymers, bands characteristic of the cr
