A high-spin level structure of the nucleus 154Tm has been established for the first time up to 6.14 MeV. The 118Sn + 40Ca reaction at 205 MeV associated with the recoil shadow method was used to identify the I π = (19)+ isomeric state at 2.74 MeV. In-beam γ-ray and conversion electron spectroscopy have been applied on the 144Sm(14N, 4n)154Tm reaction ...

Exciting excited-state aromaticity
Nature Chemistry, 2012In 1972, Baird published rules describing aromaticity and antiaromaticity in the lowest triplet excited states of annulenes. The fortieth anniversary of Baird's rules — which are the reverse of Huckel's rules for aromaticity and antiaromaticity in the ground state — ought to be celebrated before 2012 comes to an end.

Electronic Excited‐State Engineering
ChemPhysChem, 2008Long-living complexes: A CuI- bisphenanthroline complex exhibits a 15-fold prolongation of its excited state lifetime due to the planned intervention of an appended anthracene fragment (see picture). This elegant example of electronic excited-state engineering extends the range of possibilities for improving the photophysical properties of CuI ...

Chemistry – A European Journal, 2014
AbstractA new qualitative model for estimating the properties of substituted cyclopentadienes and siloles in their lowest ππ* excited states is introduced and confirmed through quantum chemical calculations, and then applied to explain earlier reported experimental excitation energies. According to our model, which is based on excited‐state aromaticity

The analysis of the fragmentation of tetramethyl-1,2-dioxetane at the end of the preceding chapter, in which three competing processes had to be considered, foreshadows the difficulty of applying the criteria of symmetry conservation to the much more complex reactions that originate in an excited state of the reactant.
