  The electron paramagnetic resonance investigations of the magnetically
concentrated crystal of KYb(MoO4)2 have been performed. The main value of
g-factors along principal local axes was determinate. The two nonequivalent
Yb3+ centers were found in ac-plane. It is shown that local symmetry of Yb3+
ion in ac-plane is not higher than rhombic. Some peculiarities in the
frequency-field dependence of an absorption line was found in H|| b
orientation.
