报告内容简介：

Combining molecules with low internal temperature and laser spectroscopy, the study of two-center H-bonding A...H is well advanced. However, much remains to be learned in a quantitative and definitive manner, especially for complexes with multiple H-bonds. Exemplary cases are in the category of alpha hydroxy carboxylic acids, i.e., the complexes of glycolic acid with water and formic acid. In glycolic acid, an intramolecular H-bond forms between the carboxyl group and the alpha OH group. The alpha OH stretching frequency may be affected upon complexing with water or formic acid. Direct study of glycolic acid complexes is unfortunately very difficult, but recently using laser spectroscopy, we managed to deduce new and subtle information for glycolic acid complexes that are important in food, cosmetics and medicine.
