The presence of a hydrogen bond may affect the excited-state dynamics of a molecule. Procedure Prepare 50 mL of a 0.0010 M solution of salicylic acid in cyclohexane. Do the same with a solution that is 0.9 M in diethyl ether and 0.0010 M in salicylic acid. Then, setting the excitation wavelength on the fluorometer to the wavelengths determined above, obtain an emission spectrum for each solution.
Calculations Tabulate the wavelengths observed for excitation and emission maxima for each solution.
Explain shifts in the maxima due to the addition of the ether.
