The Jablohski diagram plays an important role in molecular spectroscopy (Fig. 8.19). It shows three energy levels the ground state (G), the first excited singlet state (S), and the metastable in-between state. Later on researchers identified this metastable state as the lowest triplet (T). ...

Presentations of Jablohski s contribution to spectroscopy in the frame of the evolution of science and political situation in the 1930s and 1940s have been published [14, 15]. The contribution of Jacques and Francis Perrin, Jablonski, Vavilov, Levshin, Lewis, and Kasha to the definition of state diagram has been critically evaluated and the originality of each one commented by Nickel [16, 17]. The topic was discussed at the first congress on photoluminescence in Warsaw, May 20-25, 1936 (Pringsheim president, Jablonski secretary). The lively discussion that took place on that occasion has been retraced in detail by Nickel [18].
