Advances in the development of pulsed lasers provided a further breakthrough in the study of the structural dynamics of nuclei and electrons. As a result of this progress, the use of powerful femtosecond laser pulses, both for exciting the sample and for generating ultrashort (in the limit, femto- and even subfemtosecond) photoelectron bunches synchronized with optical pulses for sensing matter, made it possible to observe the coherent dynamics of nuclei and electrons in the studied samples at the required spatio-temporal scales. The huge breakthrough in chemical physics is the possibility of direct observations of reaction processes. A many-particle potential is so complex that the degree of the interaction nonadiabaticity cannot be determined with the accuracy sufficient for predicting reaction paths. How can this information and a new look at the reaction dynamics be used in the future? This question arises in connection with the development of a new conceptual foundation of natural sciences involving the convergence of experimental and theoretical tools in studies of systems of any complexity with the atomic resolution. In this approach, the `atomic-molecular' motion picture is obtained by using mutually complementary information received from simultaneous studies of the ultrafast electron (or X-ray) diffraction, spectroscopy, and the quantum dynamic theory of matter.

Keywords: ultrafast structural dynamics, ultrafast electron diffraction and microscopy, femtosecond laser radiation, electron beams of ultrashort duration
