摘　　要：一般认为,氢氧化物和氧化物的红外光谱极其简单,氢氧化锌主要是官能团区的羟基伸缩振动吸收峰和指纹区的Zn—O键弯曲振动峰,氧化锌只有指纹区的Zn-O键弯曲振动吸收,而事实上并非如此。本实验在高浓度的NaOH溶液中,用Zn(NO_3)_1·6H_2O为原料制取了Zn(OH)_2晶体,经低温干燥得ZnO,并研究了它们的红外光谱,结果表明:Zn(OH)_2中有两处双峰,ZnO中有意外的—OH吸收峰,并对其形成原因进行了探讨。It is generally acknowledged that the infrared spectra of zinc hydroxide and zinc oxide are extremely simple,and the main functional groups of zinc hydroxide are hydroxyl strentch cibration absorption peak and the fingerprint region Zn-O bond bends vibration peak,and zinc oxide only has the fingerprint region of zinc oxide Zn-O bond bends vibration absorption,but in fact it’s not true. The zinc hydroxide crystal was prepared with zinc nitrate hexahydrate as raw material in high concentration of NaOH aqueous solution,and the product was dried to form zinc oxide in low tempereture,and their infrared spectra were investigated.There were two peaks in zinc hydroxide apd -OH absorption peak in zinc oxide,and the causes of formation were investigated.
