The wavelengths of absorption of chromophores in electronic spectra are often influenced by the solvent. For example, polar solvents stabilize the ground state of n --> π transitions (n is a non-bonding orbital that is carried over into the molecular orbital scheme) more than the excited state. On the other hand, for π to π* transitions, the excited state is more stabilized. Sketch diagrams to show the changes in energy levels involved in the electronic transition when a chromophore changes from a nonpolar to a polar solvent environment and predict the shift in wavelength in each case.

Give the wavelengths of maximum absorption for each solution as shown in the spectra provided. Use the absorption wavelengths to explain why the [Ni(H2O)6] 2+ solution appears yellow-green but the [Co(H2O)6] 2+ solution appears pink. [Ni(H2O)6] 2+ maximum absorbance at 720 nm [Co(H2O)6] 2+ maximum absorbance at 510 nm

Explain why absorption spectra for atomic species consist of discrete lines at specific wavelengths rather than broad bands for molecular species.

Bohr’s Model can be used to find the wavelengths of the photons in the absorption or emission spectrum of hydrogen atom. Using that model, find the wavelengths of the 5→2, 4→2, 3→2 and 2→1 transitions. Specify the colour associated with these wavelengths when possible. To determine the colours, use tables. If the wavelength is not part of the visible spectrum, specify if it is ultraviolet or infrared.

Consider the strength of the Hβ absorption line in the spectra of stars of various surface temperatures. This is the amount of light that is missing from the spectra because Hydrogen electrons have absorbed the photons and jumped from level 2 to level 4. How do you think the strength of Hβ absorption varies with stellar surface temperature?

Why are the higher-order spectra more accurate than the first-order spectrum in determining wavelengths of light?
