Inclusive and coincidence measurements have been performed to study symmetric fragmentation of ${}_{}{}^{44}{}_{}{}^{}\mathrm{Ti}$ binary decay from the ${}_{}{}^{32}{}_{}{}^{}\mathrm{C}$ reaction at 280 MeV incident energy. Element distributions after binary decay were measured. Angular distributions and fragment correlations are presented. Total c.m. kinetic energy for the symmetric products is extracted from our data and from Monte-Carlo model calculations including Q-value fluctuations. This result was compared to liquid drop model calculations and standard fission systematics. Comparison between the experimental value of the total kinetic energy and the rotating liquid-drop model predictions locates the angular momentum window for symmetric splitting of ${}_{}{}^{44}{}_{}{}^{}\mathrm{Ti}$ between 33ħ and 38ħ. It also showed that 50% of the corresponding rotational energy contributes to the total kinetic energy values. The dominant reaction mechanism was found to be symmetric splitting followed by evaporation.
