Instrumentation for the measurement of surface vibrational sum-frequency generation (SFG) spectroscopy has been made by way of a mode-locked ND : YAG laser (Qantel YG501C-10) and a homemade parametric oscillator amplifier. Ultra high-vacuum chamber has also been constructed to use for the SFG measurement of the adsorbates or surface bonds on well-defined single crystal surfaces.The SFG spectroscopy has been made on the Langmuir-Blodgett (LB) films of cadmium arachidate in atmospheric condition and on the formate ion sorbed on MgO (100) surface under ultrahigh vacuum. It was confirmed that the developed device is capable of detecting adsorbates at 0.2 monolayers.

利用Nd：YAG锁模激光器（QantelYG 501 C-10）和自制的参量振荡放大器，研制了表面振动和频光谱测量装置。在常压下对花生酸镉LB膜进行了SFG测量，在超高真空下对吸附在MgO（100）表面的甲酸根离子进行了SFG测量。经证实，所开发的装置能够检测0.2单层的吸附物。
