我们研究了拉曼光谱作为激光遥感工具监测水中ch4的适用性。拉曼技术已经成功地用于测量水中的二氧化碳气体。本文考虑到水的光谱透过率，利用调q Nd:YAG激光在355nm（紫外区）的三次谐波检测ch4拉曼信号。在水拉曼信号的尾部检测到溶解于水中的ch4在2892 cm-1处的拉曼信号。
We examined the applicability of Raman spectroscopy as a laser remote sensing tool for monitoring CH4in water. The Raman technique has already been used successfully for measurements of CO2gas in water. In this paper, considering the spectral transmittance of water, third harmonics of Q-switched Nd:YAG laser at 355 nm (UV region) was used for detection of CH4Raman signals. The Raman signal at 2892 cm-1from CH4dissolved in water was detected at a tail of water Raman signal.
