(*) Eyring and Polanyi developed their namesake theory, and they are labeled with a double dagger.
Egyptian scientist Ahmed Zewail won a Nobel Prize for studying these entities, which can be determined using nudged elastic bands. Their position can be seen on a (**) More O'FerrallÂ–Jencks diagram, and they have a negative frequency. For protein folding, these entities are studied using phi value analysis. (*) Eyring and Polanyi developed their namesake theory, and they are labeled with a double dagger. They resemble the less stable species according to the Hammond principle. For 10 points, name these entities that possess more energy than either the reactants or products on a reaction coordinate diagram.
