Two-dimensional infrared (2D-IR) spectroscopy provides access to equilibrium dynamics with the extraction of frequency-fluctuation correlation function (FFCF) from measured spectra. Several different methods obtaining FFCF experimental spectra, such as center line slope (CLS), ellipticity, phase slope, and nodal all depend on geometrical nature 2D shape necessarily require spectral extent in or...

Abstract Series of linear tridentate PN Ph P R ‐ligands (R=Me, Et, Pln, Ph, Cyp, i Pr, Cy, t Bu) and molybdenum tricarbonyl complexes [Mo(CO) 3 ] (R=Ph, Cy,) were synthesized characterized using NMR‐, IR‐, Raman spectroscopy as well X‐ray crystallography. The influence the different phosphine donor groups ligands on bonding activation CO is investigated. Importantly, all are found to adopt a fa...

Amino acid radical generation and transport are fundamentally important to numerous essential biological processes to which small molecule models lend valuable mechanistic insights. Pyridyl-amino acid-methyl esters are appended to a rhenium(I) tricarbonyl 1,10-phenanthroline core to yield rhenium-amino acid complexes with tyrosine ([Re]-Y-OH) and phenylalanine ([Re]-F). The emission from the [R...

Methylcyclopentadienyl manganese tricarbonyl (MMT) is a fuel additive that has been marketed for use in unleaded gasoline since December 1995. The widespread use of this additive has been suggested to cause health risks, but limitations in data regarding its degradation products and their toxicity prevent an accurate evaluation. To monitor the organomanganese compounds, it is clearly advantageo...
