Chemical bonding in its myriad forms is a manifestation of
quantum mechanical principles. We strive to discover the deductive links
between these few, but subtle, principles and the infinite variety of
structures, spectra, and properties exhibited by molecular matter. There
are four stages of this research: derivation, implementation, application,
and analysis. In the first two, mathematical and computational tools are
developed for efficient and accurate calculations. Applications emphasize
interpretation of experimental problems through prediction of molecular
observables. Analytical techniques founded on the mathematical structures
of the first stage reveal conceptual connections between observables in
terms of simplified models. In each stage, we employ propagator concepts
and methods, especially those of electron propagator theory, for they stress
direct, rigorous calculation of observables and succinct expression of
model systems.
