Journal ArticleDOI
Spectroscopic and theoretical investigations of vibrational frequencies in binary unsaturated transition-metal carbonyl cations, neutrals, and anions.
TL;DR: The laser-ablation method produces mostly neutral atoms with a few percent cations and electrons for capture to make anions; in contrast, thermal evaporation gives only neutral species, so the very recent neon matrix investigations in the laboratory provide carbonyl cation and anions for comparison to neutrals on a level playing field.
Journal ArticleDOI
Probing the surfaces of heterogeneous catalysts by in situ IR spectroscopy
TL;DR: This critical review describes the reactivity of heterogeneous catalysts from the point of view of four simple, but essential for Chemistry, molecules that are considered as probes or as reactants in combination with "in situ" controlled temperature and pressure Infrared spectroscopy.
Journal ArticleDOI
The structure of active centers and the ethylene polymerization mechanism on the Cr/SiO2 catalyst: a frontier for the characterization methods.

Probing zeolites by vibrational spectroscopies
Silvia Bordiga,Carlo Lamberti,Carlo Lamberti,Francesca Bonino,Arnaud Travert,Frédéric Thibault-Starzyk +5 more
TL;DR: This review addresses the most relevant aspects of vibrational spectroscopies applied to zeolites and zeotype materials and describes the methods needed to precisely determine the IR absorption coefficients, making IR a quantitative technique.

Taming the Cationic Beast: Novel Developments in the Synthesis and Application of Weakly Coordinating Anions
TL;DR: This Review gives a comprehensive overview of the most topical weakly coordinating anions (WCAs) and contains information on WCA design, stability, and applications and methods for the incorporation of WCAs into a given system.
