    • ***
Century Dictionary and Cyclopedia
    • triatomic In chem.: Consisting of three atoms: applied to the molecules of elements where the atoms are of the same kind: as, a triatomic element; or to compounds where the atoms are unlike: as, triatomic molecules.
    • triatomic Same as trivalent.
    • triatomic Having three hydroxyl groups by which other atoms or radicals may be attached without altering the structure of the rest of the molecule: thus, glycerin is called a triatomic alcohol.

The triatomic molecule LiOB has then been studied specifically and accurately by CCSD (see e.g.
Molecules in clusters: the case of planar LiBeBCNOF built from a triangular form LiOB and a linear four-center species FBeCN
The change in the triatomic LiOB is seen to be much smaller than in the four-center case.
Molecules in clusters: the case of planar LiBeBCNOF built from a triangular form LiOB and a linear four-center species FBeCN
We have argued that it is useful to be viewed as having building blocks of (a) the bent triatomic molecule LiOB, and (b) the linear four-center molecule formed from BeCN plus F.

Most models used hyperspherical coordinates ρ, θ, φ which provide a global representation of the triatomic system: the hyperradius ρ is related to the size of the triangle formed by the three particles, while θ and φ describe its shape.
