Homework Answers
Generally, the ground state of the molecule is singlet. After absorbing light, it is excited to another singlet state. So spin multiplicity of the molecule does not change on excitation. If thr molecule undergoes ISC, then the singlet state is converted to triplet state. So the spin multiplicity change if the excited molecule undergoes ISC.

"How does the buffer capacity of the two solutions change? That is over what range of strong acid/strong base volume is the pH of the buffer resistant to change? For your two data sets of buffer data, indicate the moles of acid or base that can be added in this range." This is pertaining to a chem lab doing a combined titration of a 5 and 10mL buffer with both HCl and NaOH. I know the buffer limits of the...
