The first absorption band for H2O: Interpretation of the absorption spectrum using time dependent pictures

摘要: We examine the relation between photodissociation dynamics and form of total absorption spectrum for H2O in first band. Application an exact time dependent formalism gives a direct intuitive molecular motion spectral features. show that series weak structures on top broad continuum is due to symmetric stretch excited state. The spacing is, essentially, given by frequency associated with this motion. In addition, we present some state eigenfunctions, which provide connection structured spectrum, final product distributions, dynamics.
