2010 journal article

Ab Initio Calculation of Resonance Raman Cross Sections Based on Excited State Geometry Optimization

JOURNAL OF PHYSICAL CHEMISTRY A, 114(43), 11681–11690.

By: J. Gaff n, S. Franzen n  & B. Delley *

MeSH headings : Amino Acids, Aromatic / chemistry; Chlorine Compounds / chemistry; Cycloheptanes / chemistry; Molecular Structure; Nitrates / chemistry; Oxides / chemistry; Quantum Theory; Skatole / chemistry; Spectrum Analysis, Raman; Stilbenes / chemistry; Temperature; Toluene / chemistry
TL;DR: This method permits significant gains in the efficiency of calculating resonance Raman cross sections from first principles and, consequently, permits extension to large systems (>50 atoms). (via Semantic Scholar)

2010 journal article

Kinetic Analysis of a Naturally Occurring Bioremediation Enzyme: Dehaloperoxidase-Hemoglobin from Amphitrite ornata

JOURNAL OF PHYSICAL CHEMISTRY B, 114(43), 13823–13829.

By: H. Ma n, M. Thompson n, J. Gaff n & S. Franzen n 

MeSH headings : Animals; Biodegradation, Environmental; Biological Products / chemistry; Biological Products / metabolism; Hemoglobins / chemistry; Hemoglobins / metabolism; Kinetics; Models, Molecular; Peroxidase / chemistry; Peroxidase / metabolism; Polychaeta / enzymology; Protein Conformation; Quantum Theory; Temperature
TL;DR: The analysis suggests a dominant role for diffusion in the kinetics of DHP, and density function theory (DFT) calculations were used to address the fate of phenoxy radical intermediates. (via Semantic Scholar)

2009 journal article

Excited-State Geometry Method for Calculation of the Absolute Resonance Raman Cross Sections of the Aromatic Amino Acids

JOURNAL OF PHYSICAL CHEMISTRY A, 113(18), 5414–5422.

By: J. Gaff n & S. Franzen n 

MeSH headings : Amino Acids, Aromatic / chemistry; Cresols / chemistry; Electrons; Proteins / chemistry; Skatole / chemistry; Spectrum Analysis, Raman; Toluene / chemistry
TL;DR: The role played by substituents on the aromatic ring that decrease vibronic activity to a level that permits application of the time correlator is discussed and indicates that the L(a),(b) states are Franck-Condon active in the aromatic molecules studied. (via Semantic Scholar)
