Ionized species
WebIon-exclusion chromatography is defined [105] as a technique used to separate weak acids (e.g. carboxylic acids, amino acids), weak bases (e.g. ammonia, amines), and … The electron is ionized through multiphoton coupling with the continuum. As the intensity of the pulse is increased the excited state and the continuum are shifted in energy due to the Stark shift. At the peak of the pulse (b) the excited states go into multiphoton resonance with the ground state. Meer weergeven Ionization (or ionisation) is the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons, often in conjunction with other chemical changes. The resulting electrically … Meer weergeven Negatively charged ions are produced when a free electron collides with an atom and is subsequently trapped inside the electric … Meer weergeven Classical physics and the Bohr model of the atom can qualitatively explain photoionization and collision-mediated ionization. In these cases, during the ionization … Meer weergeven The calculations of PPT are done in the E-gauge, meaning that the laser field is taken as electromagnetic waves.
