    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 ...

    Oxygen condenses at 90.20 K (−182.95 °C, −297.31 °F) and freezes at 54.36 K (−218.79 °C, −361.82 °F). Both liquid and solid O 2 are clear substances with a light sky-blue color caused by absorption in the red (in contrast with the blue color of the sky, which is due to Rayleigh scattering of blue light).

    A gray card is a flat object of a neutral-gray color that derives from a flat reflectance spectrum. A typical example is the Kodak R-27 set, which contains one 8 in × 10 in (20 cm × 25 cm) card and one 4 in × 5 in (10 cm × 13 cm) card, each with an 18% reflectance across the visible spectrum, and a white reverse side with a 90% reflectance.
