Analysis of the Raman Spectrum of Kinked Carbon Chains Taking into Account the Model of Various End Groups

Resumo

The Raman spectra of kinked carbon chains with a set of end groups composed of hydrogen, silver, and copper atoms are calculated. It is analyzed how end groups, as well as the positions of impurity atoms in the chain, affect shifts characterizing the main peaks of the harmonic vibrations of chemical bonds between carbon atoms in polyyne- and cumulene-like (respectively, (–C≡C–)_n and (=C=)_n) chains.
