PRINCIPLES OF LIGHT ENERGY: ABSORPTION AND EMISSION

Atomic absorption and emission spectroscopy use the basic principles of the quantum

theory. The quantum theory was proposed by Max Planck around 1900 to explain

radiation of hot bodies. Five years later Albert Einstein applied the quantum principles to

the energy emitted by metals exposed to light. Neils Bohr in 1913 derived a mathematical

model of the hydrogen atom based on the quantum theory.

The atomic model with the electrons in discrete energy levels or orbitals about the nucleus

is shown in Figure 1.

This is an illustration of an atom described by the quantum theory. The discrete energy

levels of the electrons are set by nature. An electron can move up to a higher level by

absorbing a specific quantity of energy. The electron will emit that exact quantity of

energy when the electron returns to the lower level. This quantum of energy is called a

photon.
