摘要：

We have measured the spin-rotation and hyperfine structure in the ground state of the molecular radical YbF using Doppler-free laser spectroscopy in a molecular beam. The spectrum reveals that the spin-rotation constant γ of the X2 + ν=0 state is exceptionally small. At the same time, the centrifugal distortion is so enormous that γ changes sign at rotational quantum number N=60. To the best of our knowledge, this behavior is unprecedented. © 1995 The American Physical Society.
