Structure of glycolic acid determined by microwave spectroscopy
Description
The microwave spectra of all singly substituted D, 13C, and 18O species and one doubly substituted species of glycolic acid (CH2OHCOOH) have been measured and analyzed. From the moments of inertia of all species the complete molecular structure was determined. It shows an intramolecular hydrogen bond in which the hydroxyl group points toward the carbonyl oxygen of the carboxylic group with an 0...H distance of 2.11 angstrom. The structure of the free molecule in the gas phase differs largely from the molecular structure in the crystal due to strong intermolecular hydrogen bonding in the solid state
