Why is IVR in the excited state required for the isomerization reaction to take place?

Make a simple schematic sketch showing how the barrier for the reaction in Figure 1 could result from an avoided crossing. Why is the crossing avoided?

What is the sum of the quantum yields for isomerization and all fluorescence?

How can one identify the excited state IVR rate experimentally?
