Interpretation Introduction

Interpretation:

When a tiny quantity of ${\text{O}}_{\text{2}}{\text{N}}^{\text{*}}{\text{-N}}^{\text{*}}{\text{O}}_{\text{2}}$ is mixed with an equilibrium mixture of ${\text{N}}_{\text{2}}{\text{O}}_{\text{4}}\text{and}{\text{NO}}_{\text{2}}$, the ${}^{\text{15}}\text{N}$ isotope immediately becomes distributed among both ${\text{N}}_{\text{2}}{\text{O}}_{\text{4}}\text{and}{\text{NO}}_{\text{2}}$ molecules, and ${\text{N}}_{\text{2}}{\text{O}}_{\text{4}}$ it is invariably in the form of ${\text{O}}_{\text{2}}{\text{N}}^{\text{+}}{\text{-NO}}_{\text{2}}$ explanation has to be given for this observation.
