The photodissociation of aluminum clusters, Aln+ (n=3–6), has been studied over a 430–650 nm wavelength range using a tunable dye laser. The product channels are Aln−1+ + Al and Al+ + Aln−1. Photodissociation spectra have been recorded with 5 nm resolution. Several features, corresponding to transitions to different excited electronic states, are apparent in the photodissociation spectra. values for
使用可调染料激光在430–650 nm波长范围内研究了铝团簇Al n +(n = 3–6)的光解离。产物通道是Al n -1 + + Al和Al + + Al n -1。光解离光谱已以5 nm的分辨率记录下来。在光解离光谱中,明显可见到对应于跃迁到不同激发电子态的跃迁的几个特征。Al 5 + 2.20 -0.05 +0.15 eV和Al 6 +(2.35 -0.05 +0.15)的解离能的数值eV)是根据在光解离光谱中观察到的阈值以及对光产物信号的激光通量依赖性进行推论得出的。这些值比最近的从头算的结果大得多。
