摘要:
Raman spectroscopic investigations of urea inclusion compounds containing α,ω-dibromoalkane [Br(CH2)nBr; n=7–10] guest molecules are reported. Vibrational modes due to the urea confirm the structural identity of the inclusion compounds, and assignments of lattice modes due to the urea channel structure are also discussed. Investigations of the vibrational properties of the α,ω-dibromoalkane molecules included within this host structure have focused on the longitudinal acoustic mode and the C-Br stretching vibrations. The spectral bands due to the v(C-Br) mode have been used to assess the relative amounts of trans and gauche end-groups in the included α,ω-dibromoalkane molecules.
