- Assuming that the dipole moment of a molecule is zero in its electronic ground state (S0) and is µ in its first excited state (S1). If the molecule is dissolved in a polar solvent, describe the time evolution of the fluorescence spectrum following an ultrashort laser pulse excitation which excites the molecule to higher vibrational states of S1 in following cases: A. Intramolecular vibrational relaxation (IVR) is faster than solvation process; B. IVR is slower than solvation process; C. IVR and solvation occur at similar time scale.Consider the following statements as they apply to infrared spectroscopy. Decide if each is true or false. True False The quantized nature of molecular vibrations are generally understood in terms of a rigid rotor model. True False Absorption bands in infrared spectroscopy are due to vibrational and rotational-vibrational transitions in molecules. True False For a given pair of atoms, the vibrational frequency expected if they are joined by a single bond should be higher than if they are joined by a double bond. True False Because molecules in condensed phases (solids and liquid) are not free to rotate, rotational-vibrational transitions are not observed in their infrared spectra. For this reason, even at high resolution, a condensed phase spectrum is characterized by broad bands. True False Heteronuclear diatomic molecules such as HCl do not absorb infrared radiation.In this question you will use the one-dimensional particles in a box model to approximate the absorption wavelength of a cyanine dye. To determine the "box-length" for the model, determine the total length along the conjugated part of the molecule (both single and double bonds) use the following bond lengths: Typical CC bond length (both single/double bond) = 0.14 nm Typical CN bond length (both single/double bond) = 0.13 nm The structure of a cyanine dye is shown below. You need to determine the wavelength of light for a cyanine dye with n=8. Consider that both nitrogens are conjugated, so consider two CN bonds when determining box length. The left-most nitrogen has two electrons (lone pair) that count towards the number of electrons in the box, but the right-most nitrogen has no lone pair, just the double-bond. Provide your answer as the wavelength of light absorbed in units of nm. R R n R R
