利用皮秒时间分辨红外技术测量了吸附在Pt（111）单晶表面的CO的瞬态响应。瞬态漂白信号衰减被解释为给出振动激发CO的阻尼t1。瞬态吸收是根据从激发的吸附质带到泛音水平的转变来讨论的。
A picosecond time-resolved infrared technique has been used to measure the transient response of vibrationally excited CO adsorbed on the surface of a Pt (111) single crystal. Transient bleaching signal decay is interpreted as giving T 1 for damping of vibrationally excited CO. Transient absorption is discussed in terms of transitions from the excited adsorbate band to overtone levels.
