When a molecule undergoes significant thermal agitation within a mass spectrometer, which outcome regarding electron orbitals results?

A)Rydberg states' ionization threshold decreases

B)Auger decay rate becomes temperature-dependent

C)Molecular orbitals exhibit vibronic coupling✓

D)Franck-Condon factors approach zero

💡 Explanation

Increased thermal agitation induces vibronic coupling, because this mechanism reflects interaction between vibrational and electronic states; increasing thermal energy leads to changes in the molecule's vibrational modes strongly coupled to its electronic structure. Therefore vibronic coupling increases, rather than ionization changes resulting directly from thermal effects.
