Formula: C4H12KNaO10In 2013 ,《Studies on solution-grown pure and doped sodium potassium tartrate crystals》 appeared in Spectrochimica Acta, Part A: Molecular and Biomolecular Spectroscopy. The author of the article were Mathivanan, V.; Haris, M.. The article conveys some information:
A systematic anal. of the FTIR spectroscopy and Raman spectra of pure and Cu(NO3)2.3H2O doped Rochelle salt (NaKC4H4O6.4H2O) 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 C4H4O62- ion appear as doublets. For certain modes (e.g. βCH, γC(OH) and δCOO) doublets arise owing to interaction between 2 identical oscillations of 2 identical groups in COO(HO)HCCH(OH)COO2-, while for other modes (e.g. γCH, γCOa, γCOa, γCOs, δCOH and τCOO) they arise owing to crystallog. distinguishable sites for 2 identical oscillators. The effect of dopant in the pure Rochelle salt crystals is found out by using Elemental anal. The unit cell volume of pure and Cu(NO3)2.3H2O doped Rochelle salt crystals is found out from powder x-ray diffraction studies. The experimental process involved the reaction of Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate(cas: 6381-59-5Formula: C4H12KNaO10)
Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate(cas: 6381-59-5) is a ferroelectric crystal with a high piezoelectric effect and electromechanical coupling coefficient. Formula: C4H12KNaO10 It is utilized to break up emulsion in organic synthesis as well as a common precipitant in protein crystallography.
