Question

(2) The simplified electronic/vibrational/rotational energy level diagram for a molecule (called a Jablonski diagram) is shown below. Transitions involving photons are shown with wavy arrows. Arrow (a) represents 319 kJ mol-1. In this simplified example the energy levels in the singlet states and triplet states are equally spaced but in a real molecule they become closer together at higher energy. Use this diagram for questions 2-5.

Can you help me with number 4 Please and Thank You
