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 atomic orbitals on those atoms.

Antibonding Orbital

Science / Chemistry / Antibonding Orbital: A molecular orbital that can be described as the result of destructive interference of atomic orbitals on bonded atoms. Antibonding orbitals have energies higher than the energies its constituent atom MORE

Molecular Model

Science / Chemistry / Molecular Model: A representation of a molecule. The model can be purely computational or it can be an actual physical object. Stick models show bonds, ball-and-stick models show bonds and atoms, and spacefilling mode MORE

Molecular Medicine

Science / Genetics / Molecular Medicine: The treatment of injury or disease at the molecular level. Examples include the use of dna-based diagnostic tests or medicine derived from dna sequence information. MORE

Molecular Sieve

Science / Chemistry / Molecular Sieve: A material that contains many small cavities interconnected with pores of precisely uniform size. Zeolites are an example. Molecular sieves adsorb molecules that are small enough to pass through their MORE

Molecular Weight

Science / Chemistry / Molecular Weight: The average mass of a molecule, calculated by summing the atomic weights of atoms in the molecular formula. Note that the words mass and weight are often used interchangeably in chemistry. MORE
