However large the scope of normal, ground state chemistry might be, above and beyond it lies the world of excited states, each one having its own chemis try. The electronic transitions leading to the excited states, either d

Even in the more favourable cases where the optical extinction coefficient is large enough to detect the state, it is often difficult to be absolutely sure that the absorption process is due to a singlet triplet excitation and not to a normal absorption by some trace impurity.

,Vacuum Ultraviolet and Photoelectron Spectroscopy — Historical Background and Survey,electron volts is too well known to require any description here. Once the field had been opened up exploration developed along several different paths according to the particular interests of various investigators. Emission studies giving data on ionized atoms were carried out using hot spark sourc
