Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>S₂ Fluorescence</bold>: Subporphyrins are intriguing compounds, but the behavior of their higher excited states has not been studied thus far. The S₂ fluorescence of subporphyrins has now been investigated; internal conversion from the S₂ to the S₁ state was revealed to occur within approximately 300 fs. The two transition dipole moments of the degenerate S₂ states are orthogonally oriented despite the <italic>C</italic>₃ symmetry of the subporphyrin.<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg4t7bv245" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
