Answer 1

Answer:

Ultraviolet photoelectron spectroscopy (UPS) refers to the measurement of kinetic energy spectra of photoelectrons emitted by molecules which have absorbed ultraviolet photons, in order to determine molecular orbital energies in the valence region.

Explanation:

Uses

Ultraviolet photoelectron spectroscopy (UPS), using low energy photons (normally HeI, 21.2 eV, and HeII, 40.8 eV), is useful to study the valence band structures and electronic properties of many materials and to confirm the results of band structure calculations.
