← ScienceWhich outcome arises when a molecule vibrates at a frequency matching its resonant molecular frequency?
A)Selective absorption of electromagnetic radiation✓
B)Increased fluorescence quenching efficiency
C)Accelerated rate of chemical dissociation
D)Enhanced molecular electronic relaxation
💡 Explanation
When molecule vibrates at its resonant frequency, constructive interference occurs between the molecular vibrations and external energy. This leads to selective absorption of incoming elctromagnetic wave because of maximum energy exchange. Therefore absorption results, rather than radiative decay which requires additional chromophores, faster dissociation through bond breaking, or alternative relaxation mechanisms.
