Chemical bonding alteration upon electronic excitation in transition metal complexes
TL;DR: In this paper, it is shown that simple analysis in terms of bonding and anti-bonding orbitals involved in one-electron excitations is too limited to decipher the complicated mechanisms that underlie light-activated reactive channels leading to unsaturated metal complexes, meta-stable conformers or photo-switches, the properties of which are used in fast evolving fields of chemistry, biology and advanced materials.

Probing Single Molecules and Single Nanoparticles by Surface-Enhanced Raman Scattering
Shuming Nie,Steven R. Emory +1 more
TL;DR: In this article, surface-enhanced Raman scattering was used to detect single molecules and single nanoparticles at room temperature with the use of surface enhanced Raman, and the intrinsic Raman enhancement factors were on the order of 10 14 to 10 15, much larger than the ensemble-averaged values derived from conventional measurements.
