摘要：
The integrated infrared radiation (IR) absorption is measured using stretching localized vibrations of hydrogen adatoms on the silicon(111) surface. It is found that the line intensity decreases as the temperature increases. The anomalous temperature dependence is due to a strong anharmonic interaction of the H-Si stretching modes with H-Si bending modes.
