The good, the bad and the useful are all the same molecule, comprising three oxygen atoms.

Dilithium, Li, is a strongly electrophilic, diatomic molecule comprising two lithium atoms covalently bonded together.

Another is the Whiggish, anachronistic myth that Darwin's general biological thought consists of a molecule comprising just two atoms: the idea of evolution and the idea of natural selection.

A "phase" of a pure substance is the arrangement of molecules comprising the substance.

For the first time relatedness could be measured in real terms, namely similarity of the molecules comprising the genetic code.

Mass spectrometry (MS) is the science of displaying the spectra (singular spectrum) of the masses of the molecules comprising a sample of material.

These absorbing processes can be internal rotations of the molecules comprising the medium, molecular vibrations, and even the breaking of chemical bonds, again depending upon the intensity and frequency of the sonic pulses.

For example, while biology refers to macromolecules as the four large molecules comprising living things, in chemistry, the term may refer to aggregates of two or more molecules held together by intermolecular forces rather than covalent bonds but which do not readily dissociate.

A majority of materials in the Earth's crust are silicates with molecules comprising four oxygen atoms linked to one atom of silicon.

However...Dilithium does exist Dilithium, Li2, is a diatomic molecule comprising two lithium atoms covalently bonded together.
