Answer:
One needs to think about both movement and arrangement of particles in molecules based upon two different frame-of-references. Further, one needs to think about a) linear movement and b) rotational movement.
To the outside macro-world, the whole molecule might be moving and rotations.
To the movement and rotation is entirely different.
To the macro-world, the states of matter (your solid, liquid, gas) is based upon the rotational energy of the whole molecule. One must understand that a solid has specific locations for bonds, it is not moving to the macro-world, and a gas state is a molecule with enought energy (heat) to generate enough rotaitonal energy, so there is no times when a bond can form at a specific position.
