Substituted propanes

摘要: Abstract The infrared and Raman spectra of 1,2-dichloro-, 1-chloro-2-bromo- 1,2-dibromopropane were recorded as liquids, in polar non-polar solvents the crystalline state at low temperatures. spectrum a high pressure crystal was ambient temperature. Dipole measurements carried out CCl 4 C 6 H solutions. Each 1,2-dihalopropanes existed mixture three conformers liquid state, one with halogens anti position large abundance. Spectral dipole revealed comparatively larger concentration two gauche solvents. All compounds crystallized form. C-halogen stretching vibrations have been interpreted detail. Vibrational analyses tentative assignment majority bands has proposed.
