This report describes how LiI mixes with thin propanol and butanol films at cryogenic temperatures using time-of-flight secondary ion mass spectrometry and reflection absorption infrared spectroscopy. The glass transition temperature, T_g, is assignable as the uptake onset of LiI additives in the thin film interior. The uptake rate of LiI in the deeply supercooled region is small for 1-propanol and 2-butanol, but concentrated solutions are formed on a LiI film at temperatures higher than 1.2–1.3 T_g. The supercooled 2-propanol and 1-butanol are short-lived; their crystallites form complexes at the interface with LiI because of premelting.

通过与LiI的相互作用来探测丙醇和丁醇薄膜的固液转变

该报告描述了LiI如何在飞行温度下使用飞行时间二次离子质谱和反射吸收红外光谱技术与丙醇和丁醇薄膜混合。玻璃化转变温度T _g可指定为薄膜内部LiI添加剂的吸收开始时间。1-丙醇和2-丁醇在深度过冷区域中LiI的吸收率很小，但是在高于1.2-1.3 T _g的温度下，在LiI膜上会形成浓溶液。过冷的2-丙醇和1-丁醇的寿命很短；由于预熔融，它们的微晶在与LiI的界面处形成络合物。
