Differentiate between rotational energy levels, vibrational energy levels, and electronic energy levels.

The peaks in a UV-Visible spectrum are associated with which molecular changes? electronic state vibrational state rotational state translational state

What is the difference between electronic, vibrational, and rotational transitions?

7) Explain the basis of the Franck-Condon principle and how it leads to the formation of a vibrational progression.

Explain the importance of the quantization of vibrational, rotational, and translational energy as it relates to the behavior of atoms and molecules.

Arrange the following energies in order of increasing magnitude:  a) the typical energy of a covalent single bond; b) the mean molecular translational energy for a gas at room temperature; c) the mean rotational energy of a diatomic molecule at room temperature; d) the vibrational energy for a diatomic molecule at room temperature; e) the ionization energy of H.  Justify your order.

Explain Vibrational spectra of vibrating diatomic molecules

In a molecule of hydrogen iodide HI (HI is used in organic and inorganic synthesis as one of the main sources of iodine and as a reducing agent) the vibrational frequency of the molecule is 6.69x10^13 Hz. Iodine is much more heavier than hydrogen, so I can be considered immobile compared to H. Determine the expected value of the potential energy for the hydrogen atom in this molecule in the ground state. Use this to calculate the expected value of the kinetic energy.

Which of the following is responsible for absorption of ultraviolet radiation? a) Transitions among the various rotational energy levels. b) Transitions among the various vibrational energy levels. c) Transitions among various electronic energy levels. d) Transitions from electronic energy levels to higher vibrational and rotational energy levels.

Do you expect the fundamental vibrational frequency to be higher for HCl or NaCl? Explain.
