Infrared reflection absorption spectroscopy (IRAS) has been used to study CO adsorption on Au clusters ranging in size from 1.8 to 3.1 nm, supported on TiO(2). The adsorbed CO vibrational frequency blue-shifts slightly (approximately 4 cm(-)(1)) compared to that adsorbed on bulk Au, whereas the heats of adsorption (-DeltaH(ads)) increase sharply with decreasing cluster size, from 12.5 to 18.3 kcal/mol.
红外反射吸收光谱（IRAS）已被用于研究负载在TiO(2)上尺寸范围为1.8至3.1纳米的金团簇上的CO吸附情况。与吸附在块状金上的CO相比，吸附的CO振动频率略有蓝移（约4 cm(-)(1)），而吸附热（-ΔH(ads)）随着团簇尺寸的减小而急剧增加，从12.5千卡/摩尔增加到18.3千卡/摩尔。
