DFT study of Raman spectra of phosphorus-containing dendrons built from cyclotriphosphazene core

The influence of the encirclement on the line frequencies and intensities was studied and due to the predictable, controlled and reproducible structure of dendrons the information, usually inaccessible is obtained. The polarizabilities and lipophilicity of dendrons were estimated. The strong line at 1600 cm−1 show marked changes of intensity in dependence of aldehyde (СНО), ester (OСO) or azomethyne (СНN) substituents in the aromatic ring.
