The main features of the resonance scattering of electrons by molecules are described. The parameters of the resonances are calculated in the frame of two different approaches: 1) the theory of collisions in a two-body system (where applicable); 2) the quantum theory of scattering in a few-body system based on Faddeev-Yakubovsky equations. The results of calculations of the resonant cross sections of electron and atom collisions with molecules are presented. Obtained results are compared with the available experimental data and with the results of calculations based on other approximations. In addition some biological applications (e.g. properties biopolymer molecules) are presented. Application of the results for determination of biopolymer molecule parameters is presented.
