ROTATIONAL SPECTRUM OF K39F BY THE MOLECULAR BEAM ELECTRIC RESONANCE METHOD

Abstract

Transitions between the J = 0 and J = 1 rotational states of K39F have been measured by means of the molecular beam electric resonance method. The following rotational constants have been determined (all frequencies in Mc/sec):[Formula: see text]The quadrupole interaction constants eqQ as measured in the J = 1 state are found to be[Formula: see text]The equilibrium internuclear distance obtained directly from Be is[Formula: see text]The electric dipole moment in the ν = 0 state is[Formula: see text]
