the closely spaced negative charges associated with the phosphate groups
No. That is characteristic of a nonmetal, specifically the halogens (group 17) on the periodic table.

When an electron in an excited state falls to a lower energy level, it releases energy in the form of a photon. The energy of this photon corresponds to the difference between the two energy levels. This process is fundamental to phenomena such as atomic emission spectra and is responsible for the colors emitted by various elements when they are heated or energized. The released photon can have specific wavelengths, which are characteristic of the element involved.
Vibrational quantum number indicates the vibrational energy level of a molecule, while rotational quantum number describes the rotational energy level. Both quantum numbers are used to describe the quantized energy states of a molecule in quantum mechanics.
The cell itself is responsible for chemical reactions. Chemical reactions are the basis of life, and all parts of the cell work together to make them happen. Specifically the enzyme and mitochondria are often cited as being responsible. The enzymes are proteins that create a binding surface for the chemical reaction and speed the process. The mitochondria act as a digestive system and energizer for the cell.

The characteristic of each type of radiation in the electromagnetic spectrum that is determined by its wavelength is its energy level.

An emitted photon is typically generated when an electron transitions from a higher energy level to a lower energy level within an atom or molecule. This transition releases energy in the form of a photon.

When a molecule doesn't stand stable or it obtain energy or forced to get energy it's electron upgrade from lower level of energy cycle to higher level of energy cycle.By excreting energy it's electron can also fall down from higher energy cycle to lower level of energy cycle . This excreting energy turn into light .
When light strikes a chlorophyll molecule, electrons in the chloroplast get excited.
By phosphorylation. Attach a phosphate group, with it's two oxygen anions, to a molecule and you will raise it's potential energy level.
UV-vis active molecules must have easily deformed electron clouds. This requirement is met for molecules with lots of pi-bonds that are directly connected together, or conjugated.
