Mode-dependent enhancement and intramolecular dynamics via vibrationally mediated photodissociation

Vibrationally mediated photodissociation has been shown to control bond cleavage in molecules and probe their dynamics on the ground and excited potential energy surfaces. The application of this method to two seven-atom molecules illustrates surprising vibrational energy localization in methylamine (CH3NH2), a molecule with a torsional degree of freedom and unique information regarding intramolecular vibrational energy redistribution for the C-H methyl stretches of propyne (CH3C equivalent to C-H).
