What weak peak transitions shown in the uv vis spectrum
Accepted Answer
Weak peak transitions in a UV-Vis spectrum are often due to forbidden transitions. These transitions involve an electronic excitation that is less likely to occur according to selection rules. Examples include transitions that involve a change in spin multiplicity (e.g., singlet to triplet) or transitions that require a change in both the spin and orbital angular momentum. The intensity of a peak is proportional to the probability of the transition, so weak peaks correspond to low probability transitions.
