The bond in a homonuclear diatomic molecule is non-polar.
2.
In symmetrical homonuclear diatomic molecules, the permanent electric dipole moment vanishes.
3.
A homonuclear diatomic molecule is one composed of two atoms of the same NO.
4.
For homonuclear diatomic molecules, the index g or u denotes the existence of a parity of the total wave function.
5.
Being the lightest stable neutral homonuclear diatomic molecule after H 2, and the helium dimer, dilithium is an extremely important model system for studying fundamentals of physics, chemistry, and Morse / Long-range variety.
6.
Since the rotational motions ( about both vertical axis and horizontal axis passing through the inversion center ) preserve the symmetry of the molecule, the matrix elements of D between different rotational states must vanish for symmetrical homonuclear diatomic molecules, unless the electronic state itself changes.
7.
In this sense, a van der Waals surface of a homonuclear diatomic molecule can be viewed as an pictorial overlap of the two spherical van der Waals surfaces of the individual atoms, likewise for larger molecules like methane, ammonia, etc . ( see images ).
8.
In the special case of a homonuclear diatomic molecule, there is an extra symmetry since in addition to the axis of symmetry provided by the internuclear axis, there is a centre of symmetry at the midpoint of the distance between the two nuclei ( the symmetry discussed in this paragraph only depends on the two nuclear charges being the same.
