In order to understand the nature of room temperature ionic liquids which are expected to become nobel materials, vaporation machanism and structures of some room temperature ionic liquids were investigated by low-temperature matrix-isolation infrared spectroscopy as a experimantal method with aids of high level quantum chemical calculations. Especially, we focused on protic ionic liquids simply made by a mixing of one acid and one base. Although it had been usually considered that the parent acid and base are released in the gas phase from protic ionic liquid by proton transfer from anion to cation, another vaporization mechanism that anion-cation pair directly evaporates from the protic ionic liquid composed of strong acid and strong base were found in this study.

为了了解有望成为诺贝尔材料的室温离子液体的性质，以低温基体隔离红外光谱为实验方法，借助高水平量子化学计算，研究了一些室温离子液体的汽化机理和结构。 特别是，我们专注于通过一种酸和一种碱的混合简单地制成的质子离子液体。 尽管通常认为母体酸和碱是通过质子从阴离子到阳离子的转移而从质子离子液体中以气相形式释放出来的，但本研究发现了另一种汽化机制，即阴离子-阳离子对直接从强酸和强碱组成的质子离子液体中蒸发。
