Atomic orbital
In quantum mechanics, an atomic orbital is a mathematical function that describes the wave-like behavior of either one electron or a pair of electrons in an atom.

Born–Oppenheimer approximation
In quantum chemistry and molecular physics, the Born–Oppenheimer (BO) approximation is the assumption that the motion of atomic nuclei and electrons in a molecule can be separated.

Chemical bond
A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds.
New!!: Molecular physics and Chemical bond · See more »
Chemical physics
Chemical physics is a subdiscipline of chemistry and physics that investigates physicochemical phenomena using techniques from atomic and molecular physics and condensed matter physics; it is the branch of physics that studies chemical processes from the point of view of physics.

Electromagnetic spectrum
The electromagnetic spectrum is the range of frequencies (the spectrum) of electromagnetic radiation and their respective wavelengths and photon energies.

Electrostatic deflection (molecular physics/nanotechnology)
In molecular physics/nanotechnology, electrostatic deflection is the deformation of a beam-like structure/element bent by an electric field.

Energy level
A quantum mechanical system or particle that is bound—that is, confined spatially—can only take on certain discrete values of energy.
New!!: Molecular physics and Energy level · See more »
Infrared
Infrared radiation (IR) is electromagnetic radiation (EMR) with longer wavelengths than those of visible light, and is therefore generally invisible to the human eye (although IR at wavelengths up to 1050 nm from specially pulsed lasers can be seen by humans under certain conditions). It is sometimes called infrared light.

Micrometre
The micrometre (International spelling as used by the International Bureau of Weights and Measures; SI symbol: μm) or micrometer (American spelling), also commonly known as a micron, is an SI derived unit of length equaling (SI standard prefix "micro-".

Molecular dynamics
Molecular dynamics (MD) is a computer simulation method for studying the physical movements of atoms and molecules.
New!!: Molecular physics and Molecular dynamics · See more »
Molecular modelling
Molecular modelling encompasses all methods, theoretical and computational, used to model or mimic the behaviour of molecules.

Molecular orbital
In chemistry, a molecular orbital (MO) is a mathematical function describing the wave-like behavior of an electron in a molecule.
New!!: Molecular physics and Molecular orbital · See more »
Molecule
A molecule is an electrically neutral group of two or more atoms held together by chemical bonds.
New!!: Molecular physics and Molecule · See more »
Physical chemistry
Physical Chemistry is the study of macroscopic, atomic, subatomic, and particulate phenomena in chemical systems in terms of the principles, practices, and concepts of physics such as motion, energy, force, time, thermodynamics, quantum chemistry, statistical mechanics, analytical dynamics and chemical equilibrium.

Rigid rotor
The rigid rotor is a mechanical model that is used to explain rotating systems.
New!!: Molecular physics and Rigid rotor · See more »
Scattering
Scattering is a general physical process where some forms of radiation, such as light, sound, or moving particles, are forced to deviate from a straight trajectory by one or more paths due to localized non-uniformities in the medium through which they pass.
New!!: Molecular physics and Scattering · See more »
Spectroscopy
Spectroscopy is the study of the interaction between matter and electromagnetic radiation.
New!!: Molecular physics and Spectroscopy · See more »
Spectrum
A spectrum (plural spectra or spectrums) is a condition that is not limited to a specific set of values but can vary, without steps, across a continuum.
New!!: Molecular physics and Spectrum · See more »
Theoretical chemistry
Theoretical chemistry is a branch of chemistry, which develops theoretical generalizations that are part of the theoretical arsenal of modern chemistry, for example, the concept of chemical bonding, chemical reaction, valence, the surface of potential energy, molecular orbitals, orbital interactions, molecule activation etc.
New!!: Molecular physics and Theoretical chemistry · See more »
Ultraviolet
Ultraviolet (UV) is electromagnetic radiation with a wavelength from 10 nm to 400 nm, shorter than that of visible light but longer than X-rays.
New!!: Molecular physics and Ultraviolet · See more »
Wavelength
In physics, the wavelength is the spatial period of a periodic wave—the distance over which the wave's shape repeats.
