Spectroscopy within the system. There are many different types

is the study of the interactions of electromagnetic radiation, or light, with
matter in order to gain information about the atoms or bonds present within the
system. There are many different types of spectroscopic ways of doing things;
however, most of the ways of doing things are based on the absorption or
emission of photons from the material being studied. The applications of
spectroscopy span a variety of fields of study and can allow scientists to,
among huge numbers of other things, decide/figure out the elemental
(combination of different substances, objects, people, etc.) of a nearby dwarf
star, the chemical identity of an unknown white powder sample, whether a
transfected (tiny chemical assembly instruction inside of living things) has
been expressed, or the types of individual bonds within a molecule.
Spectroscopy is the study of how light interacts with matter. It allows
scientists in a broad organized row of fields to study the composition of both
very large and very small systems. Each spectroscopic way of doing things is unique;
however, most of the widely used ways of doing things are based on one of three
(important events or patterns of things): the absorption of light by matter,
the emission of light by matter, or the scattering of light by matter. A photon
can behave as both a particle and a wave. For most spectroscopic ways of doing
things, the wave nature of the photon is the most critical because the
wavelength of light being gave off/given off, soaked up (like a towel), or
scattered is where the information about the sample is contained. Absoprtion
spectroscopy involves the Absorption of photons by matter and can give
information about the types of atoms or bonds in a molecule. Usually, a given
material will soak up (like a towel) clearly stated/particular wavelengths of
light and will reflect or transmit all the other wavelengths. Emission
spectroscopy involves the emission of photons from a sample on excitation.
Scattering deals with light that is in elastically scattered from a sample,
meaning that the wavelength of light bouncing off the sample is not the same as
the wavelength of light that was shined on the sample.
