DISSOCIATIVE RECOMBINATION Meaning and
Definition
-
Dissociative recombination refers to a fundamental process that occurs in atomic and molecular physics whereby a free electron interacting with an ion results in the breakup or dissociation of the ion. This process typically takes place in low-temperature plasmas, such as those found in astrophysical environments like stellar atmospheres or interstellar clouds, as well as in laboratory experiments.
During dissociative recombination, the electron is captured by the ion, leading to the formation of a temporary excited state. This excited state then undergoes decay, leading to the fragmentation or dissociation of the ion into its component parts, such as atoms, molecules, or atomic or molecular fragments.
This phenomenon plays a crucial role in various chemical processes and astrophysical phenomena. In the context of astrophysics, dissociative recombination is important for understanding the chemical composition and energy balance of celestial bodies. In laboratory settings, it helps researchers gather information on the structure, dynamics, and properties of atoms and molecules.
Dissociative recombination is a complex process that depends on a variety of factors, including the specific ion involved, the energy of the electron, and the quantum state of the system. It can occur through various mechanisms, such as direct dissociative recombination, indirect dissociative recombination via electronic excitation, or dissociative recombination involving predissociation. Detailed theoretical models and experimental investigations are employed to accurately describe and understand dissociative recombination processes.

Etymology of DISSOCIATIVE RECOMBINATION
The word "dissociative recombination" is derived from the combination of two terms: "dissociative" and "recombination".
1. Dissociative: The term "dissociative" comes from the Latin word "dissociātus", which is the past participle of the verb "dissociāre" meaning "to separate" or "to disconnect". In chemistry, "dissociation" refers to the process of breaking apart a compound into its constituent molecules or ions.
2. Recombination: The term "recombination" comes from the Latin word "recombināre", which is a combination of "re-" (meaning "again" or "back") and "combināre" (meaning "to unite" or "to combine"). In general, "recombination" refers to the process of joining or combining previously separated things.
