When generated in a chemical reaction it will quickly convert into a more stable molecule.
We can test this theory by using matrix isolation and then employing standard techniques such as in the study of stable molecules.
Molecular nitrogen, a very stable molecule, is even better.
Benzene is a more stable molecule than would be expected without accounting for charge delocalization.
These are stable molecules that have been trapped at low temperature (see sulfur monoxide article).
The greater the number of contributing structures, the more stable the molecule.
This observation of greater delocalization in less stable molecules is quite general.
H@C is found to be a stable molecule.
One must put energy into a stable molecule to get it to break apart into atoms.
It's not a very stable molecule, but it takes a lot of power to create it.
