12. D, but other alternatives are possible. For simplicity, the electric field polarizations and dipole moment are taken to be parallel.
13. The excited-state interference population can be detected by measuring the time- and frequency-integrated fluorescence. The quadralinear contribution to the population can be isolated from the total fluorescence by separately detecting and subtracting signal contributions arising from one-, two-, and three-pulse induced fluorescence. See Reference 1.
14. Even combinations of pulses contribute to the ground state probability amplitude and higher odd combinations of pulses cannot contribute to a quadrilinear signal.

17. The definition of the pulse propagator in Eq. (9) differs from that used in Reference 2 by a factor of -i. This change in definition accounts for the difference in form of Eqs. (7) and (8) from the corresponding expressions, Eqs. (9) and (10) of Reference 2.
