53. Because of the detection scheme employed (see the Experimental Section), the shown signals are not normalized (δT). The parallel component was about half the level of prenormalized form of the pump-probe signal shown in Figures 2 and 3. Therefore, it was consistent with the pulse intensity conditions described in the Experimental Section.
