Rotational Spectroscopy

Rotational Spectroscopy. To a stationary observer, a rotating polar molecule looks like an oscillating dipole which can stir the electromagnetic field into oscillation. This picture is the classical origin of the gross selection rule for rotational transitions.

Forming Compounds:

Forming Compounds:. Bonding. Bonding. When two atoms collide, valence electrons on both atoms interact. A chemical bond is created between the atoms if the valence electrons rearrange so that the new compound has less energy than before.
