Abstract

Vibrational progressions due to radiative decay of A1P(v' = 0,2,3,5,6,8) e3S(v' = 3,5,12), a'3S(v' = 11,14),d3D(v' = 5) to the ground state and of e3S(v' = 3,7,9,11,12), d3D(v' = 3,7,11) to the a3P state were obsd. for selective excitation of A1P(v' = 0, ..., 8). The intersystem crossing rate consts., the bottle necks, pathways and rate consts. for internal conversion in the triplet levels and the triplet-singlet radiative rate consts. are explained by an intramol. mixing of electronic states and electron-phonon coupling with the matrix.

Internal conversion

Internal conversion is an atomic decay process where an excited nucleus interacts electromagnetically with one of the orbital electrons of an atom. This causes the electron to be emitted (ejected) from the atom. Thus, in internal conversion (often abbreviated IC), a high-energy electron is emitted from the excited atom, but not from the nucleus. For this reason, the high-speed electrons resulting from internal conversion are not called beta particles, since the latter come from beta decay, where they are newly created in the nuclear decay process.

Ground state

The ground state of a quantum-mechanical system is its stationary state of lowest energy; the energy of the ground state is known as the zero-point energy of the system. An excited state is any state with energy greater than the ground state. In quantum field theory, the ground state is usually called the vacuum state or the vacuum. If more than one ground state exists, they are said to be degenerate. Many systems have degenerate ground states.

Carbon monoxide

Carbon monoxide (chemical formula CO) is a poisonous, flammable gas that is colorless, odorless, tasteless, and slightly less dense than air. Carbon monoxide consists of one carbon atom and one oxygen atom connected by a triple bond. It is the simplest carbon oxide. In coordination complexes, the carbon monoxide ligand is called carbonyl. It is a key ingredient in many processes in industrial chemistry. The most common source of carbon monoxide is the partial combustion of carbon-containing compounds.
