Absorption spectra of 4-nitrophenolate ions measured in vacuo and in solution

Chemphyschem. 2009 Jun 2;10(8):1207-9. doi: 10.1002/cphc.200900174.

Abstract

From blue to red: While four pi-conjugated nitrophenolates absorb within a relatively narrow region in solution, they cover the entire visible spectrum when isolated in vacuo [picture: see text]. The work combines gas- and solution-phase spectroscopy and provides the first benchmark of theoretical excitation energies for nitrophenolates.
