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.
No. That is characteristic of a nonmetal, specifically the halogens (group 17) on the periodic table.
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.
Energy is transferred from pigment molecule to pigment molecule in the protein complex through resonance energy transfer, leading to excitation of a special chlorophyll a molecule called P680. This excitation of P680 causes the release of an electron, which is then transferred to the primary electron acceptor, initiating the electron transport chain in photosynthesis.

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 .
By phosphorylation. Attach a phosphate group, with it's two oxygen anions, to a molecule and you will raise it's potential energy level.
When light strikes a chlorophyll molecule, electrons in the chloroplast get excited.
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.
An oxygen atom has 6 electrons in its outermost energy level. In a water molecule, each hydrogen atom can share one electron with the oxygen atom, forming a covalent bond. This results in the oxygen atom having a total of 8 electrons in its outermost energy level.
