One of the central challenges for synthetic chemists is to impose control over free radicals. Highly reactive molecules with an unpaired electron, free radicals may be familiar to you; these are the ...

Scientists experimented with nitric oxide, a highly stable molecule of supreme importance in science. NO is highly reactive and a free radical, meaning a single, unpaired electron is present in its ...

Photochemical reactions begin by absorption of energy in the form of light, and involve formation of free radicals and transient excited states whose physical and chemical properties are very ...
