The CH radical is a very reactive radical which, under most conditions, has a very short lifetime.
From Gerhard Herzberg
The visible and near-ultraviolet emission spectrum of the CH radical has been known ever since spectra of an ordinary Bunsen burner have been taken.
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.
It is very difficult to find appropriate words to say 'thank you' for an honour like the Nobel Prize. It is the supreme honour that a scientist can receive. Some of the giants in physics and chemistry have received this prize.
