Which outcome occurs when the energy of an incident electron matches a molecule's unoccupied molecular orbital energy?

💡 Explanation

When the incident electron energy matches an unoccupied molecular orbital, resonant electron capture occurs because electron temporarily occupies a new orbital causing internuclear distances change, increasing vibrational energy. Therefore molecular vibrational energy increases, rather than kinetic energy reduction, elastic scattering or electron ejection which require different excitation processes.
