Abstract: Abstract: A systematic analysis of the Fourier transform infrared spectroscopy and Raman spectra of pure and Cu(NO3)23H2O doped Rochelle salt (NaKC4H4O64H2O) in terms of the standard frequency correlations, deuteration shift and typical nature (with respect to intensity and width) of bands due to different modes is reported. The bands due to the internal modes (excluding some skeletal modes) of the ion appear as doublets. For certain modes (e.g. β CH, γ C(OH) and δ COO) doublets arise owing to interaction between two identical oscillations of two identical groups in COO(HO)HCCH(OH)COO2−, while for other modes (e.g. γ CH, , , δ COH and τ COO) they arise owing to crystallographically distinguishable sites for two identical oscillators. The effect of dopant in the pure Rochelle salt crystals is found out by using Elemental analysis. The unit cell volume of pure and Cu(NO3)23H2O doped Rochelle salt crystals is found out from powder X-ray diffraction studies. [Copyright &y& Elsevier]
