An analysis and an interpretation of the reported photoelectron spectra of the nitrate anion, NO 3 -

Key Points

• This research aims to analyze and interpret photoelectron spectra of the nitrate anion (NO3-).
• Utilized traditional photoelectron spectra methods.
• Employed slow photo-electron velocity-map imaging of cryogenically cooled ions (cryo-SEVI) for measurements.
• Conducted a comparative analysis between traditional and modern methods.
• Demonstrated enhanced resolution and accuracy in measuring photoelectron spectra using cryo-SEVI.
• Identified distinct spectral features attributable to electronic transitions in the nitrate anion.
