From: Manipulating photodissociation dynamics via an embedding UV pulse

(a) The UV pump (ωpump, gray dashed)-UV embedding (ωembed, red dash-dotted) scenario for a diatomic CH+. The embedding pulse effectively couples the unpopulated vibrationally excited levels of the ground state X1Σ+ with the dissociative continuum C1Σ+, resulting in the formation of UIVRs, which are detected by the pump pulse in photofragment spectra. (b) The pump-embedding scenario in the lowest order of the Floquet frame involves a long embedding field, whose electric envelope couples the lifted potential with the dissociative potential.
