To describe the ground (gr) and excited states of even-even deformed nuclei with the phenomenological model, which takes into account the mixing ground $(gr)$, $0^{ +}_{ 2}(\beta_1)$--, $0^{ +}_{ 3}(\beta_2)$--, $2^{ +}_{ 1}(\gamma_1)$--, $2^{ +}_{ 2}(\gamma_2)$-- and $K^{ \pi}=1^{ +}_{ \nu}$ rotational bands the calculation has been done for the isotope $^{ 172}Yb$. The energy specterum is described. The reduced probability of electric quadrupole, monopole and dipole magnetic transitions from the states $0^{ +}_{ \nu}$ and $2^{ +}_{ \nu}$ - bands to the ground $(gr)$ state band is calculated. A non adiabatic effect in the energy and electromagnetic characteristics is discussed.
