Wavefunction

Science / Chemistry / Wavefunction: A mathematical function that gives the amplitude of a wave as a function of position (and sometimes, as a function of time and/or electron spin). Wavefunctions are used in chemistry to represent the behavior of electrons bound in atoms or molecules.

Orbital

Science / Chemistry / Orbital: A wavefunction that describes what an electron with a given energy is doing inside an atom or molecule. MORE

Basis Set

Science / Chemistry / Basis Set: A set of mathematical functions that are combined to approximate the wavefunctions for electrons in atoms and molecules. MORE

Basis Function

Science / Chemistry / Basis Function: A mathematical function that can be used to build a description of wavefunctions for electrons in atoms or molecules. MORE

Atomic Orbital

Science / Chemistry / Atomic Orbital: A wavefunction that describes the behavior of an electron in an atom. MORE

Molecular Orbital

Science / Chemistry / Molecular Orbital: A wavefunction that describes the behavior of an electron in a molecule. Molecular orbitals are usually spread across many atoms in the molecule, and they are often described as a combination of atomi MORE
