Аннотация:We study the dynamic equations for H2X type molecules with one bending degree of freedomwithin the framework of the soft body model. The dynamic equations for the components ofangular momentum and Euler angles under different initial conditions are numerically integrated.Initially, the tennis racket effect was studied only for rigid spinning tops. Our investigationfocuses on the impact of molecular non-rigidity on the tennis racket effect. It was shown that non-rigidity leads to the multi-center nature of the tennis racket effect. Moreover, it was establishedthat non-rigidity also affects the shape of the phase trajectories, making them more curved.
