Query: Attosecond Molecular Spectroscopy and Dynamics   The present review addresses the technical advances and the theoretical
developments to realize and rationalize attosecond-science experiments that
reveal a new dynamical time scale ($10^{-15}$-$10^{-18}$ s), with a particular
emphasis on molecular systems and the implications of attosecond processes for
chemical dynamics. After a brief outline of the theoretical framework for
treating non-perturbative phenomena in Section 2, we introduce the physical
mechanisms underlying high-harmonic generation and attosecond technology. The
relevant technological developments and experimental schemes are covered in
Section 3. Throughout the remainder of the chapter, we report on selected
applications in molecular attosecond physics, thereby addressing specific
phenomena mediated by purely electronic dynamics: charge localization in
molecular hydrogen, charge migration in biorelevant molecules, high-harmonic
spectroscopy, and delays in molecular photoionization.
