Measurements of mid-infrared (MIR) absorption spectra of water and heavy water were carried out by fiber-optic evanescent wave spectroscopy, using silver halide (AgClBr) infrared fibers. Such measurements were performed for the first time on one sample, during the solid-liquid phase transition. From the variation of the spectra with temperature we found a new isosbestic point (at 3280 cm(-1) for H(2)O or at 2475 cm(-1) for D(2)O) and we identified five components of the O-H (O-D) stretch band. These phenomena have provided new information about the molecular structure of water.
利用卤化银（AgClBr）红外光纤，通过光纤倏逝波光谱法对水和重水的中红外（MIR）吸收光谱进行了测量。在固 - 液相转变过程中，首次对一个样品进行了此类测量。从光谱随温度的变化中，我们发现了一个新的等吸收点（H₂O 在 3280 cm⁻¹处，D₂O 在 2475 cm⁻¹处），并确定了 O - H（O - D）伸缩带的五个成分。这些现象为水的分子结构提供了新的信息。
