Isotopic substitution changes the rotational energy levels of a molecule. This phenomenon can be used for precise evaluation of the atomic weight of isotopes. The first line (J = 0) in the pure rotational spectrum of 12C160 and 13C160 are found to be 3.84235 and 3.67337 cm-1, respectively. Calculate the precise atomic weight of 13C given that the precise atomic weight of 160 is 15.9994 and that of 12C is 12.011. (Consider the molecules as rigid rotor and isotopic substitution does not affect the bond length).

Atomic Structure

The basic structure of an atom is defined as the component-level of atomic structure of an atom. Precisely speaking an atom consists of three major subatomic particles which are protons, neutrons, and electrons. Many theories have been stated for explaining the structure of an atom.

Shape of the D Orbital

Shapes of orbitals are an approximate representation of boundaries in space for finding electrons occupied in that respective orbital. D orbitals are known to have a clover leaf shape or dumbbell inside where electrons can be found.
