It is shown that Raman spectra of PVA-CuCl2 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. Keywords: low-dimensional systems, SERS.
