Evidence for the Involvement of Acid/Base Chemistry in the Reaction Catalyzed by the Type II Isopentenyl Diphosphate/Dimethylallyl Diphosphate Isomerase fromStaphylococcus aureus
Biochemistry, 47(8), 2547–2558.
Contributors: C. Thibodeaux *, S. Mansoorabadi *, W. Kittleman*, W. Chang* & H. Liu*
MeSH headings : Acids / chemistry; Amines / chemistry; Carbon-Carbon Double Bond Isomerases / chemistry; Carbon-Carbon Double Bond Isomerases / metabolism; Catalysis; Flavin Mononucleotide / metabolism; Hemiterpenes; Hydrogen-Ion Concentration; Isoenzymes / chemistry; Isoenzymes / metabolism; Models, Biological; Spectrophotometry, Ultraviolet; Staphylococcus aureus / enzymology
TL;DR:
UV-vis spectral analysis of the IDI-2 reaction revealed the accumulation of a reduced neutral dihydroflavin intermediate when the reduced enzyme was incubated with IPP or DMAPP, suggesting that the C2-H bond of IPP is cleaved in the rate determining step and that general acid/base catalysis may be involved during turnover.

2008 journal article
Photophysics of the Platinum(II) Terpyridyl Terpyridylacetylide Platform and the Influence of FeII and ZnII Coordination
Inorganic Chemistry, 47(15), 6796–6803.
Contributors: M. Muro*, S. Diring *, X. Wang*, R. Ziessel* & F. Castellano*
TL;DR:
The chelation of Zn (II) to 1 is acid-base in nature, and its Lewis acidity renders the highest occupied molecular orbital level in 1 much less electron-rich, which induces a blue shift in both the absorption and emission spectra, indicating that these emitting states are inverted relative to room temperature.

Slow Cation Transfer Follows Sensitizer Regeneration at Anatase TiO2 Interfaces
Journal of the American Chemical Society, 130(35), 11586–11587.
Contributors: A. Staniszewski*, S. Ardo *, Y. Sun *, F. Castellano* & G. Meyer *
TL;DR:
The data demonstrate that slow (micros to ms) cation transfer follows regeneration to yield the sensitizer that was initially photoexcited, and the transient absorption features were found to report on photoinduced variations in the local electronic environment of the Ru(II) sensitizers-TiO2 interface that were induced by ion transfer.

Photophysical Studies of the Trans to Cis Isomerization of the Push−Pull Molecule: 1-(Pyridin-4-yl)-2-(N-methylpyrrol-2-yl)ethene (mepepy)
The Journal of Physical Chemistry A, 112(36), 8310–8315.
TL;DR:
Comparison of the experimental results with theoretical studies provide evidence for a mechanism in which the trans to cis isomerization of mepepy results in the loss of a hydrogen bond between a water molecule and the pyridine ring ofmepepy.
