The lowest energy level state is called ground level (E0 = 0), the remaining energy level called the excited state level, while the lowest energy excited state is referred to as the first excited state. Under normal conditions, atoms in the ground state, extranuclear on the respective lowest energy orbital motion. If some external energy such as solar energy supplied to the ground state atom direct butyl acetate, when the outside light energy E is exactly equal to the energy difference between the ground state atom in the ground state E and a higher energy level between the atoms will absorb this a characteristic wavelength of light butyl acetate, the outer electron transitions from the ground state to the corresponding excited states. The original light provides energy spectral lines after missing some features of spectral lines offer butyl acetate, resulting atomic absorption spectrometry. Energy electronic transitions to a higher energy level in an excited state later, but the electron excited state is unstable, after about 10-8 seconds later, the excited electrons return to the ground state or other low energy level, and when the electrons transition absorption released in the form of light out, this process is called atomic emission spectrometry. Atomic absorption spectroscopy visible radiation energy absorption process, while atomic emission spectrometry process releases energy radiation. We minimum energy spectrum of hydrogen atom as the lowest energy, the energy state is called the ground state, the corresponding level is called the base level. When an atom in some way from the ground state is lifted to a higher energy state on, the internal energy of atoms increases, the atoms will be excess energy to this form of light emitted, so have the emission spectrum atoms, Conversely absorption spectrum is generated. This change in state atomic energy is not continuous, but the quantum nature, which we call the transition between the atomic level. In the emission spectrum of the molecule, the main contents of the study is the emission spectrum of diatomic molecules. In the molecule, the energy electronic states is 50 to 100 times more than the shelf butyl acetate vibrational energy, and vibrational energy is 50 to 100 times greater than the energy transfer dynamics. Therefore, in the transition between electronic states of molecules, is always accompanied by vibrational transitions and rotational transitions, so many spectral lines on the densely together to form the band spectrum.
