Molecular Beam Investigation of Rotational Transitions. II. The Rotational Levels of KBr and Their Hyperfine Structure

Abstract

The molecular beam electrical resonance method has been used to study the hyperfine structure of the first rotational state in ${\mathrm{K}}^{39}$ ${\mathrm{Br}}^{79}$ and ${\mathrm{K}}^{39}$ ${\mathrm{Br}}^{81}$.
