The B3LYP structures and relative energies of the rotational isomers of oxalic acid are found very similar to MP2 results, confirming that the most stable isomer is the doubly intramolecular hydrogen-bonded C2h structure E1, with four other planar isomers within 6 kcal/mol.

By direct titration of a highly diluted sample, after filtration if necessary, the chlorine in the two fractions was determined. On the assumption that the oxalic acid distributed itself in the same ratio as the chlorine, it could be calculated for the entire sample by a determination on the drained fraction.
