Chlorophyll is a conjugated molecule meaning it has a series of alternate double and single covalent bonds between it carbons. Pigment's conjugated bonds share electrons in pi orbitals across the whole structure and the number of bonds in space the determines wavelength of light to be absorbed.
Chlorophyll's conjugated bonds are found in the porphyrin ring, made up of a cyclic tertapyrrole and in the conjugated side chain, which forms a long hydrocarbon tail to the heme ring. Electrons move readily along a conjugated bond series like they do in copper wire.
When a photon of just the right amount of energy strikes an electron resonating in the pigment, the electron can absorb the photon and get promoted to a higher quantum level. The photon must have just the exact amount of energy to boost the electron from its current level to its new level or it cannot be absorbed. When the incoming photon is just right to promote an electron, in that pigment, the newly energized electron resonates along the bonds at the higher energy level where it can pass to the electron transport chain.
