Classical Model of Surface Enhanced Infrared Absorption (SEIRA) Spectroscopy
Gao, Y., Aspnes, D. E., & Franzen, S. (2022, January 10). JOURNAL OF PHYSICAL CHEMISTRY A, Vol. 1.

author keywords: Oxidation; Mass spectrometry; Reaction mechanism; Marine; Chlorinated molecules; Stopped-flow
MeSH headings : Animals; Hemoglobins / chemistry; Polychaeta; Peroxidases / metabolism; Peroxidase / chemistry; Hydrogen-Ion Concentration
TL;DR:
As pH was lowered, DHP-A appeared to have a higher peroxidase activity than D HP-B, an unprecedented result, and the fact that there are multiple processes contributing to both kinetics and yield of TCP oxidation complicates interpretation of these data.

The role of the 2-amino group in regulating the competition between these pathways was elucidated in order to explain how the striking difference in reactivity under irradiation arises from the greater spin density on the 6-nitreno-9-methyl-9 H -purin-2-amine, which essentially eliminates the barrier to oxidation observed in 6-Nitreno -9- methyl-9H -purine.

TL;DR:
The improvement in the fit between matrix isolation data and a model of adenine with a single water was not as dramatic as the fit seen for the polycrystalline data, but the fact that a single hydrogen-bonded water shifted the spectra of the model to a closer fit than that of isolatedAdenine is important.

TL;DR:
The results show that band III is vibronically coupled to the Soret band, and the coupling of band III to modes with strong rhombic distortion of the heme macrocycle calls into question the hypothesis that the axial iron out-of-plane displacement is primarily responsible for the structure-dynamics correlations observed in myoglobin.

Proximal ligand motions in H93G myoglobin
EUROPEAN JOURNAL OF BIOCHEMISTRY, 269(19), 4879–4886.

TL;DR:
The data presented here further substantiate the conclusion that a conformationally driven ligand switch exists in photolyzed H93G-*CO and suggest that ligand conformational changes in response to dynamic motions of the globin on the nanosecond and longer time scales are a general feature of the H 93G proximal cavity mutant.

TL;DR:
The data presented here do not appear to support the presence of pi-back-bonding or an inverse trans effect of NO binding in Mb mutants that alter the electrostatic environment of the heme pocket, leading to the observation that nu(N-O) and nu(Fe-NO) are not quantitatively correlated for the MbNO complexes presented here.

A model for maturation of the procaspase-3 dimer is proposed based on results from circular dichroism, fluorescence anisotropy, and FTIR studies, which suggest that the pro-peptide adopts a beta-structure when in contact with the protein, but it is a random coil when free in solution.
