WebIt can be clearly observed that the average binding energies of Pd–Ir clusters increase as the proportion of Ir becomes larger, because Ir–Ir and Pd–Ir bonds are stronger than Pd–Pd bonds. From this figure, we can obtain the stability order of Pd–Ir clusters: Pd core Ir shell > sandwich-Pd > Pd cup Ir ball > ordered > Pd ball Ir cup ... WebThe infrared spectrum of dimethyl sulfoxide shows an absorption peak at 1050 cm -1, which arises from the sulfur-oxygen bond. If a Lewis acid bonds to the sulfur atom, the contribution of resonance structure 1 decreases, and the SO stretching frequency increases.
