A systematic analysis of the IR and Raman spectra of Rochelle salt (NaKC,H,O, * 4H,O) 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 C,H,O:-ion appear as doublets. For certain modes 1e.g. PCH, vC(OH) and &oo)] doublets arise owing to interactions between two identical oscillations of two identical groups in COO(HO)HCCH(OH)COOz-, while for other modes (e.g.vCH , vso, vso, 6,,, and zcoo) they arise owing to crystallographically distinguishable sites for two identical oscillators.

An analysis of the Raman and infrared spectra of di-potassium tartrate hemi-hydrate (DKT), K2C4&06*fH20, is reported. It has been inferred that the C4H40:-ion and H 2 0 molecule in a DKT crystal occupy points of C, site symmetry. Various units of C4H402-ion/(H,O molecule) located at crystallographically distinguishable positions in this crystal do not appear to be different in their structure or the force fields governing their vibrational dynamics.
