Which of the following events may occur when IR radiation is absorbed?
1. Relative nuclear spins of nucleii with non-zero Io's are changed.
2. Bonding electrons are promoted to higher energy molecular orbitals.
3. More intense IR absorptions occur for those bonds having greater dipole moment changes with bond lengthening in a vibration.
4. Vibrational amplitudes of bonds are increased.
5. Intra-molecular bond angles are changed.
I tried 2,3, and 5 as true, but it was wrong. I can't figure out what I'm doing wrong.
