The given data supports isobutyric acid anhydride as described below:
The 1H NMR gives us an indication that this compound is symmetrical in nature. Especially, the doublet at 1.25 ppm (1,1, and 1',1' protons) and septet at 2.65 ppm (2 and 2' protons) points to an isopropyl group. IR absorptions at 1810 and 1770 cm-1 suggest an anhydride group.
