What is an absorbent spectrum?

The absorption spectrum is obtained by exposing the sample of a clean compound to light. The amount of energy collected by molecules in the sample is brought as a spectroscope scans the wavelengths from red to ultraviolet. Chemists use absorbent spectrum to identify unknown organic and transient metal compounds. The absorption spectra uses biologists to relation to wavelengths of light absorbed during photosynthesis into various plant pigments. In order to appear colored, the object must absorb energy in this band. The atomic structures that do so are called chromophores and have two main types: temporary metal ions and conjugated organic bonds, such as occurring in double and triple bonds on carbon. These excited states are not stable and energy is released rapidly. Transition metals appear in the middle of the periodic table.

Conjugated organic molecules often consist of a series of double pairs of bonding in a long chain.Lycopene, with 12 double steam, is a red pigment of tomatoes and beta-carotene with 11 pairs is an orange pigment of carrots. Molecules absorb the energy of photons of one wavelength along the length of the molecule.

The

absorption spectrum shows a wide response rather than a single sharp peaks that would be expected to be absorbed by individual wavelengths of light. This is due to the absorption of energy without quantum by other parts of the molecule. The spectra are sufficiently characteristic to be used for qualitative identification of compounds. Organic laboratories have absorption references.

The

atomic absorption devices of the flame measure the concentration of metal solutions by evaporating the metal ion. By depriving the sample of other ingredients, metal atoms will be in their basic state. When metal gas is exposed to light, sharp response will be reported as an external shell electrorone absorbs the energy of a specific wavelength. With this technique is possible quantumITIVE Analysis of metals.

Biologists use a study of absorption spectrum to identify wavelengths absorbed in the photosynthetic process. By correlation of photosynthetic output with wavelength and known absorption spectrum for each plant pigment, the activity of each pigment can be examined. Similar techniques are used for other light -induced reactions.
