摘要

In this study, a highly sensitive and versatile method based on photothermal spectroscopy has been developed to monitor the molecular density at a liquid/liquid interface. The excitation under the total internal reflection (TIR) condition results in a formation of a thin thermal lens elongated along the interface. In order to measure the thermal lens effects effectively and to reduce the background, the probe beam is irradiated parallel to the interface and its deflection is detected, which is called an TIR-optical beam deflection (TIR-OBD). As a result, the detection limit in TIR-OBD is about 2 orders lower than that of TIR-thermal lens spectroscopy, in which the irradiation of the probe beam is perpendicular to the interface.
