High resolution spectroscopy of some gaseous transition metal containing diatomic molecules
This thesis reports studies of the electronic spectra of some gaseous diatomic molecules containing transition metals. The (0,0) bands of the C³Π - X³Δ, e¹Π - X³Δ and f¹Φ - a¹Δ electronic transitions of niobium nitride (NbN) have been recorded at sub-Doppler resolution by intermodulated …

Magnetic resonance of cobalt(II) and iron(III): A Schiff's base and heme proteins
… 0.30 MHz, and they are interpreted by the ground electron configuration--$\rm (dx\sp2-y\sp2)\sp2(dz\sp2)(dxz)\sp2(dyz)\sp1.$

A study of the nature and origin of the minialbumins to be found in cadmium-poisoned animals
… cadmium is by distillation from zinc ores. The electron configuration of cadmium is 4d105s2, and it forms simple bipositive cations only. There are no ligand field stabilization effects in cadmium ions, and the stereochemistry is, therefore, determined solely by size and electrostatic and …

High resolution spectroscopy of the Vanadium oxide B⁴ [pi] -X⁴ [sigma] ⁻ (0,0) Band
… by the v = 2 level of the a²Σ⁺ state. The electron configuration of the a²Σ⁺ state was determined to be (4sσ)¹(3dδ)² because of the large Fermi contact interaction which arose from an unpaired electron having primarily metal 4s atomic orbital character. The transition frequencies were fit …

Gold-nickel surface alloy chemistry with oxygen and carbon monoxide
… 80 K are separately measured via high-resolution electron energy loss spectroscopy, as a function of increasing gold coverage. The progression from adsorptive to non-adsorptive behavior is rationalized by constructing two mutually consistent adsorption models for O₂ and CO that account for the …

Geometric and Electronic Structure Sensitivity of Methyl and Methylene Reactions on α-Cr₂O₃ and α-Fe₂O₃ surfaces
Structural and electronic effects in hydrocarbon reactions over metal oxides have been examined by comparing the reactions of methyl (-CH₃) and methylene (=CH₂) fragments on three different oxide single crystal surfaces: α-Cr₂O₃(101̅2), α-Cr₂O₃(0001), and α-Fe₂O₃(101̅2). The intermediates have been …

Aspects of organometallic chromium nitrosyl chemistry
… and cyclic voltammetry. The 17-valence electron CpCr(N0)(L)X compounds undergo ligand substitution in donor solvents, S, forming either CpCr(N0)(S)I or [CpCr(N0)(L)(S)]I complexes, depending on the conditions used. The CpCr(N0)(L)X complexes display irreversible reduction behavior in …

Lewis-base Thioacetamide assisted crystallization of lead-free perovskite solar Cells for improved Efficiency
… 1.4 eV. Due to similar ionic radii and outermost electron configuration to Pb2+, Sn-based PSCs have been a magnet for significant rearrangement in the lead-free PSC community. However, Sn-based perovskites have poor stability and low efficiency in PVSCs because they oxidize and decompose …

Anderson Localization in Two-Channel Wires with Correlated Disorder: DNA as an Application
… research studied the Anderson localization of electrons in two-channel wires with correlated disorder and in DNA molecules. It involved an analytical calculation part where the formula for the inverse localization length for electron states in a two-channel wire is derived. It also involved a …

Catalytic hydrofunctionalization and small molecule reactivity at a low-valent cobalt center supported by a bis(carbene) CCC pincer ligand
… of noble metals to engage in well-defined two-electron redox events that are amenable to analysis and prediction. In contrast, the reactivity of first-row transition metals is mostly characterized by one-electron redox changes that can be deleterious and has precluded the systemic incorporation …

The femtosecond m-edge approach to the photodynamics of iron(II) complexes
… polypyridyl ligands also have d6 ground-state electron configuration and are strong absorbers of visible light, and are consequently considered to hold promise as affordable alternatives to their more expensive ruthenium and iridium analogs. However, conventional iron complexes with polypyridyl …
