    Study Notes

    Spectroscopy

    • The study of the interaction of electromagnetic radiation with matter, such as atoms and molecules, is within the scope of spectroscopy.
    • Molecular spectroscopy refers to the study of the interaction of electromagnetic radiation with molecules.

    Molecular Spectra

    • The spectra that arises from the transition of electrons between rotational and vibrational energy levels in addition to electronic transitions is called vibronic spectra.

    Molecular Spectroscopy

    • Molecular spectroscopy provides a clear image of molecular structure, bonding, and dynamics.

    Electromagnetic Radiation

    • When a subatomic particle, such as an electron, is accelerated by an electric field, it emits electromagnetic radiation.

    Atomic Spectra

    • The transition of electrons between different energy levels within an atom gives rise to atomic spectra.
