The CH radical is a very reactive radical which, under most conditions, has a very short lifetime.

At first, I was able to use a Bunsen burner attached to my mother's gas stove, but the use of the kitchen as a laboratory came to an abrupt end when a minor explosion involving hydrogen sulphide spattered the newly painted decor and changed the colour from blue to dirty green!

For polyatomic free radicals and ions, one is dependent both for the ground states and the excited states on the study of electronic spectra to obtain the shapes and the geometrical parameters.

Every time I sat in a chemistry lesson, I thought, 'What am I doing this for? I don't ever want to be in a job that involves a Bunsen burner.'

Radicals can be found in any environment.

Things that burn very brightly, we wonder how long they can keep burning.

For under certain conditions the chemical atoms emit light waves of a specific length or oscillation frequency - their familiar characteristic spectra - and these can come in the form of electromagnetic waves only from accelerated electric quanta.

We should note that this latter type of shift was successfully amplified to a considerable extent by Russian physicists using the intense light of a ruby laser whose wavelength is close to that of a transition of the potassium atom.

The atoms become like a moth, seeking out the region of higher laser intensity.

Radical Chic, after all, is only radical in Style; in its heart it is part of Society and its traditions.
