Hydrogen peroxide ( H2O2) is a nonplanar molecule with (twisted) C 2 symmetry; this was first shown by Paul-Antoine Giguère in 1950 using infrared spectroscopy. [9] [10] Although the O−O bond is a single bond, the molecule has a relatively high rotational barrier of 386 cm −1 (4.62 kJ / mol) for rotation between enantiomers via the trans ...
