Chlorophyll A: Chlorophyll A is the principal pigment that captures sunlight for photosynthesis. Chlorophyll B: Chlorophyll B is the accessory pigment that collects sunlight and passes into chlorophyll A. Absorption Range. Chlorophyll A: Chlorophyll A absorbs the light in the range of 430 nm to 660 nm.
Stages of photosynthesis. When chlorophyll a absorbs light energy, an electron gains energy and is 'excited'. The excited electron is transferred to another molecule (called a primary electron acceptor). The chlorophyll molecule is oxidized (loss of electron) and has a positive charge.hen light energy is absorbed by a chlorophyll molecule its electrons gain energy and move to higher energy levels in the molecule (photoexcitation). Sufficient energy ionises the molecule, with the electron being 'freed' leaving a positively charged chlorophyll ion. This is called photoionisation.
