Glycerol is UV/vis spectroscopically characterized by using suitable solvatochromic polarity probes spanning a wide temperature range of 353 to 77 K. For the first time we find experimental evidence that, when the solvent preserves its internal structure in a broad range of temperatures, all solvatochromically derived solvent parameters (i.e., SP, SdP, SA, and SB) also maintain their values unchanged. On the basis of these solvatochromic measurements, it is shown that, below 180 K, glycerol efficiently blocks the molecular structure of conformationally flexible solutes.

甘油在353至77 K的温度下的溶剂化：其溶剂变色特征及其用于阻断构象柔性结构的分子结构

使用适合的溶剂变色极性探针在353至77 K的宽温度范围内对甘油进行紫外/可见光谱表征。我们首次发现实验证据表明，当溶剂在很宽的温度范围内保持其内部结构时，所有溶剂变色派生的溶剂参数（即SP，SdP，SA和SB）也保持其值不变。根据这些溶剂变色法的测量结果表明，在180 K以下，甘油有效地阻断了构象柔性溶质的分子结构。
