Triatomic molecule
Encyclopedia
Triatomic molecules are formed by three atoms. Examples include H2O, CO2, HCN etc.
of a triatomic molecule can be determined in specific cases.
In the previous formulas, M is the total mass of the molecule, mA and mB are the masses of the elements A and B, k1 and k2 are the spring constants of the molecule along its axis and perpendicular to it.

Symmetric linear molecules
A symmetric linear molecule ABA can perform:- Antisymmetric longitudinal vibrations with frequency
- Symmetric longitudinal vibrations with frequency
- Symmetric transversal vibrations with frequency
In the previous formulas, M is the total mass of the molecule, mA and mB are the masses of the elements A and B, k1 and k2 are the spring constants of the molecule along its axis and perpendicular to it.

Triatomic hydrogen
Triatomic hydrogen or H3 is an unstable molecule composed of three atoms of hydrogen.The neutral molecule can be formed in a low pressure gas discharge tube.It can break up in the following ways: H_3 \quad \longrightarrow \quad H_3^+ \ + \ e^-...
