From Centrosymmetry to Noncentrosymmetry: Precise Structural Regulation and Characterization on ZnHPO3·2H2O Polymorphs

“…The observed absorption band between 1112 and 995 cm –1 can be assigned to the symmetric and asymmetric stretching vibrations of the P–O and Zn–O bonds . Additionally, the absorption peaks observed around 574 cm –1 can be attributed to the bending pattern of the P–O bonds. , In the Raman spectrum, stretching vibration and bending vibrations of the P–H bond were observed at 2434–2471 and 1059 cm –1 , respectively. Additionally, absorption peaks at 1011 and 1162 cm –1 indicate the symmetric and asymmetric stretching of the P–O bond, while an absorption peak at 567 cm –1 demonstrates the flexion vibration of the P–O bond .…”
