Caption: A molecular graphics artist's impression of the chemistry of atmospheric ozone depletion, prompted by the appearance of the so-called "hole" (a blue disc here) over Antarctica every Austral spring since its discovery in 1980. In this image ozone molecules (triatomic oxygen) appear in blue. Among them are three examples of different chlorofluorocarbons (CFCs) or Freons, chemicals used in aerosols & refrigerants that are believed to be the cause of ozone depletion. From left to right in yellow, green & purple are Freons 11, 12 & 14. Ultraviolet radiation penetrating the depleted atmosphere appears as white lines.
