  We have examined the influence of rotation on the potential energy and the
transport coefficients of the collective motion (friction and mass
coefficients). For axially symmetric deformation of nucleus Th-224 we have
found that at excitations corresponding to temperatures T > 1 MeV the shell
correction to the liquid drop energy practically does not depend on the angular
rotation. The friction and mass coefficients obtained within the linear
response theory for the same nucleus at temperatures larger than T=2 MeV are
rather stable with respect to rotation provided that the contributions from
spurious states arising due to the violation of rotation symmetry are removed.
At smaller excitations both friction and mass parameters corresponding to the
elongation mode are growing functions of rotational frequency.
