Raman scattering behavior of hybrid polymeric complexes of polyvinyl alcohol with CuCl$_2$ and Cu(OH)$_2$/CuO

It is shown that Raman spectra of PVA-CuCl$_2$ and PVA-Cu(OH)$_2$/CuO complexes recorded at 514.5 nm excitation have similar shape with prominent background and broad band at 1590 cm$^{-1}$. They are identical to spectra of PVA complexes' with other inorganic compounds, spectra of different carbonaceous materials – polyacetilene, graphite and nanotubes and PVA's SERS spectrum. This result is regarded as a consequence of one-dimensionality of investigated materials. Raman bands of PVA, Cu(OH)$_2$/CuO, and CuO are present in PVA-Cu(OH)$_2$ complexes' spectra at 1064 nm excitation.
