Need help, please. The absorption spectrum for tyrosine clearly is a smooth function of wavelength, yet theelectronic energy levels in tyrosine are discrete. Why is the tyrosine absorption spectruma smooth function?Select one or more:O Molecular vibrations can subtract energy from an electronic energy levelIt is not possible to detect discrete photon energies.Bond rotations can subtract energy from an electronic energy levelBond rotations can add energy to an electronic energy levelMolecular vibrations can add energy to an electronic energy level

The absorption spectrum is a graphical representation of how a substance absorbs light at different wavelengths. When electromagnetic radiation, such as visible or ultraviolet light, interacts with atoms or molecules, it can cause electronic transitions—movements of electrons between energy levels.In an absorption spectrum:X-axis: Represents the wavelength or frequency of light.Y-axis: Indicates the extent of absorption or transmission of light.Distinctive peaks or bands in the spectrum correspond to specific electronic transitions.The absorption spectrum for a molecule like tyrosine appears as a smooth function of wavelength, even though the electronic energy levels in the molecule are discrete. This phenomenon can be explained by the presence of molecular vibrations and rotations.Molecular vibrations and rotations can interact with electronic transitions, leading to a broadening of the absorption bands. When a molecule absorbs a photon and undergoes an electronic transition to a higher energy level, the energy is not solely associated with the electronic motion. Instead, the molecule as a whole may undergo vibrational and rotational motions. This interaction between electronic, vibrational, and rotational degrees of freedom results in a range of energy levels within the absorption band, making the absorption spectrum appear as a smooth function.Therefore, the correct statements are:Molecular vibrations can subtract energy from an electronic energy level: Vibrations can indeed affect the energy levels of electronic transitions.Bond rotations can subtract energy from an electronic energy level: Similarly, rotations can also influence the energy levels of electronic transitions.Molecular vibrations can add energy to an electronic energy level: Vibrations can contribute both to adding and subtracting energy from electronic transitions.These processes collectively contribute to the broadening of absorption bands and the observed smoothness in the absorption spectrum of molecules like tyrosine.
