energy of the lowest unoccupied molecular orbital

symbol: $E_{\rm{LUMO}}$
https://doi.org/10.1351/goldbook.11440
The energy of the lowest energy level of a molecule that contains no electrons in the ground state, sometimes used as a measure of electrophilicity in QSAR models.
Note: Also known as the energy of the lowest empty molecular orbital, \(E_{\rm{LEMO}}\).
