How does ethane rotation affect IR selection rules?

Ethane Rotation Effects on IR Spectra 1. Rotation blurs conformations into average 2. Vibrations change overall dipole moment 3. IR sees time-averaged dipole wiggles 4. Symmetric and asymmetric modes still appear 5. Intensities depend on averaged dipole changes 6. Slow rotation reveals conformation-specific differences Common Mistakes Interpreting Ethane IR Spectra 1. Thinking vibrations disappear due to rotation 2. Treating instantaneous symmetry as observed symmetry 3. Assigning peaks to single geometry without evidence Visit https://www.gumballdegree.com to learn more. Want to learn more about this topic?
