The shaped pulses were shown to be phase-sensitive atintensities too low to access different higher electronic states,and so these pulses apparently steer the isomerization throughconstructive and destructive interference effects, a mechanismsupported by observed signatures of vibrational coherence.

变过形的脉冲在低强度下显得很敏感，这种强度很小，因此很难进入更高的电子状态。于是，很明显地，这些脉冲能给通过破坏性和建设性的干扰效应来操控异构化作用。观测到的振动一致信号更支持了这样一种机制。
