For each reaction shown below follow the curved arrows to complete each equationby showing the structure of the products. Identify the acid, the base, the conjugated acid andconjugated base. Consutl the pKa table and choose the direciton theequilibrium goes. However show the curved arrows. Please explain if possible.
A molecule shows peaks at 1379, 1327, 1249, 739 cm-1. Draw a diagram of the energy levels for such a molecule. Draw arrows for the possible transitions that could occur for the molecule.
In the diagram imagine exciting an electron, what are its various options for getting back to the ground state?
What process would promote radiation less decay?
What do you expect for the lifetime of an electron in the T1 state?
Why is phosphorescence emission weak in most substances?
What could you do to a sample to enhance the likelihood that phosphorescence would occur over radiationless decay?
