Consider the molecules nitrogen dioxide (NO2) and dinitrogen trioxide (ONNO2). Nitrogen dioxide is reddish orange in color, while dinitrogen trioxide is blue in color. a. Based on the observed colors of nitrogen dioxide and dinitrogen trioxide, which molecule is most likely to have the smallest energy difference for its HOMO → LUMO electronic transition? Explain your answer. b. UV-visible absorption spectral data for dinitrogen trioxide indicate an absorbance maximum at 720 nm. There are no additional peaks observed at longer wavelength. Based on this information, calculate the energy of its HOMO → LUMO electronic transition. Report your answer in units of eV.
