本文用卤化碱压片法研究了不稳定偏硼酸酯单体及其环状三聚体阴离子的红外光谱。这些阴离子是通过KBH_4的氧化或KB（OH）_4的脱水直接在基质卤化物中制备的。本文对环状三聚体的基本振动频率作了初步的归属，虽然用碱金属卤化物压片法测定固体化合物的红外光谱是光谱实验室的标准方法，只有少数几次尝试报道了这种技术用于光谱学研究，反应动力学34或观察不稳定化学物质的红外光谱。[3]圆盘法的这些明显的扩展并没有引起光谱学家的注意，也许是因为他们认识到了与这种技术有关的固态反常现象，以及解释环境对溶质种类振动模式的影响的性质的困难。虽然这些问题的解决方案是必要的最终一个完整的解释实验结果所获得的磁盘方法，我们希望在这里表明，即使没有这些解决方案，
The alkali halide pressed disk method has been used to observe the infrared spectra of the unstable metaborate monomer and its cyclic trimer anions. These anions were prepared directly inthe host halide matrices by the oxidation of KBH4 or by the dehydration of KB (OH) 4. A tentative assignment of the fundamental vibrational frequencies of the cyclic trimer is presented.Although the use of alkali halide pressed disks2 3to obtain the infrared spectra of solid compounds is a standard procedure in spectroscopic laboratories, only a few attempts havebeen reported in which this tech-nique was employed to study spectroscopically the re-action kinetics34 in the solid state or to observe the infrared spectra of unstable chemical species. 3b These obvious extensions of the disk method havenot re-ceived much attention of spectroscopists, perhaps because of recognition by themof solid state anomalies4 associated with this techniqueand of the difficulty in interpreting the nature of the environmental effects5 on the vibrational modes of the solute species. While solutions to these problems are necessary ultimately for a complete interpretation of experimental results obtained by the disk method, we wish to show here that even without these solutions the pressed disk
