提供了使用同步加速器红外辐射的耦合电化学和光谱仪接口的描述。所描述的接口可以实现电化学系统时间分辨红外光谱研究所需的精确计时。整个接口使用商用 FTIR 光谱仪生成的一系列晶体管-晶体管逻辑触发信号，以可重复且可调节的时序来调节控制、电化学和红外信号的记录。该仪器已使用薄层电化学电池和通过显微镜光学器件聚焦的同步加速器光进行了测试。苯醌/二羟基苯醌氧化还原对的时间分辨响应作为仪器功能的示例进行了说明。 (C) 2011 年美国物理研究所。 [doi:10.1063/1.3624693]
A description of a coupled electrochemical and spectrometer interface using synchrotron infrared radiation is provided. The interface described allows for the precise and accurate timing needed for time-resolved IR spectroscopic studies of electrochemical systems. The overall interface uses a series of transistor-transistor logic trigger signals generated from the commercial FTIR spectrometer to regulate the recording of control, electrochemical, and IR signals with reproducible and adjustable timing. The instrument has been tested using a thin-layer electrochemical cell with synchrotron light focused through microscope optics. The time-resolved response of the benzoquinone/dihydroxybenzoquinone redox couple is illustrated as an example of the instrument's capability. (C) 2011 American Institute of Physics.
