Theory - Physical basis of the algorithm:

.Ions (compounds) are characterized by their concentrations, internal and kinetic energy distributions, and are connected by competitive, consecutive and reversible reactions. Reaction rates are calculated by RRKM. Changes in the internal and/or kinetic energy (distribution) may occur due to chemical reactions and/or by acceleration, radiative and/or collisional energy transfer. Collisional effects are described by single collisions and collision rate. Several (single) collision models are used: long-lived complex, partially inelastic collisions, and partially inelastic collisions incorporating collisional cooling. Energy transfers are described by distributions. The simultaneity of these processes is taken into account using the master equations

The concept of MassKinetics is described in detail in the review paper: L. Drahos and K. Vékey, J. Mass Spectrom. 36, 237 (2001) .
