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.

This problem deals with fluorescence and phosphorescence. (a) Someone says that when the quantum yield of molecule (donor) is reduced to 50% of its original value because of the presence of a quencher (acceptor) allowing fluorescent resonance energy transfer, then (i) the efficiency of FRET is 50%, and (ii) the distance between donor and acceptor is 50% of R0. Support these claims if they are true. Correct these claims if they are false. (b) Five mini questions. (i) Fluorescence combines which two of the following transitions: electronic, vibrational, rotational? (ii) Which is helped more by heavy atoms in the emitting molecule: fluorescence, phosphorescence?(iii) The Frank-Condon principle plays a role in which process: absorption, vibrational relaxation, intersystem crossing? (iv) What type of shift is observed for fluorescence: redshift, blueshift? (v) Selection rules indicate that which process is forbidden: fluorescence, phosphorescence, both, neither?
