Radio‐frequency transitions between the hfs levels of the J=1 rotational state in 85Rb19F have been observed using a molecular beam electric resonance spectrometer. From these spectra we have obtained values for the constant eq1Q1, which characterizes the interaction between the electric quadrupole moment of the Rb nucleus with the molecular electric‐field gradient; for the constants c1 and c2 which characterize the magnetic interaction between the Rb and F nuclei, respectively, and the rotational angular momentum J of the molecule; and for the constants c3 and c4 which describe the magnetic coupling of the two nuclear spins. Measurements have been made on the first‐five vibrational states. The results for v=0 areeq1Q1=(−70.342±0.001)MHz,c1=(+0.52±0.02)kHz,c2=(+10.615±0.06)kHz,c3=(+0.80±0.06)kHz,c4=(+0.15±0.05)kHz.Values of these constants for v=1, 2, 3, and 4 are given with somewhat less precision
