The existence of rotating quasimolecular hyperdeformed states formed in the entrance channel of capture reactions of light nuclei is predicted within a rotational liquid-drop model, including the nuclear proximity energy. The l-dependent capture barrier heights and positions, as well as the angular momentum, the energy, and the moment of inertia ranges of these very deformed high-spin states, are given for the reactions 13C + 13C, 16O + 16O, 28Si + 12C, 28Si + 16O, 24Mg + 24Mg, 28Si + 24Mg, 28Si + 28Si, 28Si + 40Ca, 40Ca + 40Ca, 40Ca + 48Ca, 48Ca + 48Ca, and 58Ni + 58Ni. Analytical formulas are provided for any reaction between light nuclei.
