Heavy ozone - a difficult puzzle to solve
Article Abstract:
Heavy isotopes of ozone, mainly 49-O3 and 50-O3, exist in the atmosphere in larger proportions than would be expected from the relative abundance of the three oxygen isotopes. Gregory Gellene has developed a quantitative prediction scheme based on metastable states of the ozone molecule.

Methyl chloroform and the atmosphere
Article Abstract:
The Montreal Protocol has led to an actual decrease in atmospheric abundance of methyl chloroform, a short-lived man-made chemical. Methyl chloride abundance figures have helped estimate abundances of the hydroxyl radical, an important parameter in atmospheric chemical calculations.

Photochemistry of ozone: surprises and recent lessons
Article Abstract:
The electronically excited oxygen atom O(1D), which is produced by the solar photolysis of ozone, is crucial to hydroxyl formation in the lower atmosphere. O(1D) reactes with H2O and CH4 to become a major source of the hydroxyl radical OH.
