我们提出了一个实验测试的吸附物引起的变化之间的预测关系的红外反射率和直流电阻率的金属。我们测量了在300- 2000 cm ~（-1）频率范围内，O和CO在Cu（100）上以及CO在Ni（100）上反射率的绝对变化，并将其与已发表的相应薄膜系统的电阻率变化进行了比较。对于两个吸附在铜的结果是一致的一个简单的模型的基础上散射的传导电子的吸附物。然而，对于Ni上的CO，反射率的变化远小于预测。
We present an experimental test of a predicted relationship between adsorbate-induced changes in the infrared reflectance and dc resistivity of a metal. We have measured the absolute change in reflectance for O and CO on Cu(100) and for CO on Ni(100) over the frequency range 300--2000 cm[sup [minus]1] and compared it with published resistivity changes for the corresponding thin-film systems. For the two adsorbates on Cu the results are consistent with a simple model based on scattering of conduction electrons by the adsorbate. For CO on Ni, however, the reflectance change is much smaller than predicted.
