Abstract

Concepts have been developed which favor low-energy absorption in the near-infrared (NIR) region. These include metal-metal charge transfer (inter-valence charge transfer) transitions of mixed-valent species, radical ion compounds (anions, cations), and mixtures thereof. Recent examples from ruthenium coordination chemistry are presented in order to illustrate analysis and assignment of such NIR transitions.
