← ScienceWhich consequence occurs when diatomic oxygen absorbs specific wavelengths during spectroscopic analysis?
A)Increased ligand field splitting arises
B)Electron transition boosts fluorescence levels
C)Vibrational excitation distorts molecular geometry✓
D)Non-bonding orbitals cause triplet splitting
💡 Explanation
Vibrational excitation deforms the molecule because photon absorption promotes electrons to higher energy levels, thereby energizing molecular bonds with infrared photons. Molecular geometry is distorted therefore, rather than electronic rearrangement due to higher intensity absorption.
