摘　　要：水热法合成水晶与天然水晶的物理化学性质相似、内含物少见,常规检测方法无法鉴别。本论文采用德国布鲁克(Bruker)TENSOR27红外光谱仪测试分析,发现合成无色水晶以3585cm^(-1)谱带为特征;烟水晶特征吸收峰在3300~3000cm^(-1)附近,而合成烟水晶位于3600~3300cm^(-1)附近;合成黄水晶仅有5200cm^(-1)吸收峰,黄水晶不具有此特征吸收;紫水晶具有5228cm^(-1)、4450cm^(-1)特征谱带,合成紫水晶在4000~3000cm^(-1)内有特征吸收峰;合成绿水晶仅有5200cm^(-1)吸收峰。Hydrothermal synthesis crystal and natural crystal has the same physical and chemical properties ？ rare inclusion. Conventional detection methods can？t identify. In this paper, using Infrared spectroscopy analysis, Synthesis of colorless and transparent crystals found in 3585 cm 1 band is characterized; Smoky crystals ab-sorption peak at 3300 - 3000 cm 1 ,and the synthetic smoky crystals is located at 3600 - 3300 cm 1 ; Synthetic citrine have 5200 cm 1 absorption peak, citrine doesn？t have this characteristic absorption; There are 5228 cm 1,4450 cm 1 characteristic spectrum of amethyst,the synthesized have characteristic absorption peak in the 4000 - 3000 cm 1 ; Synthetic green crystal is only 5200 cm 1 absorption peak.
