Suppose one of your students tells you that they collected an electronic (maybe vibronic) spectrum of formaldehyde with a high energy transition (but not a Rydberg transition), and it must be the (1b1 to 5a1) transition coupled with the B2 out-of-plane bending vibration.
Convince yourself that this is possible or not possible. Your answer must include the following:
Analysis of the pure electronic transition orbital allowedness.
Analysis of the spin allowedness of the proposed transition. You need to show the spin multiplicities as part of the answer.
Analysis of whether or not the B2 vibration could result in an allowed vibronic transition as your fellow student described. You can use the v=0 to v’=1 transition in this problem.
