FIG. 2.

Response of the setup to a fast steplike bleaching upon excitation of aqueous . Temperature, . Excitation energy: at 532 nm. Monitoring light at 448 nm polarized at magic angle with respect to the excitation pulse polarization. Average of 256 transients. Upper trace: without amplifier. Lower trace: with amplifier. Inset: response of the detection system to scattered light from the excitation laser. Upper trace: without amplifier. Lower trace: with amplifier.

FIG. 3.

Response of the setup to exponentially decaying absorption changes upon excitation of in 60% (w/w) glycerol/water. Monitoring light at 488 nm. (a) At different angles (increasing from bottom to top) between the polarizations of the monitoring light and the excitation pulse, . (b) At different temperatures (increasing from bottom to top). Polarizations of the monitoring light and the excitation pulse parallel.

FIG. 4.

Determination of the detection limit for exponentially decaying absorbance changes. (a) Response of the setup to exponentially decaying absorption changes upon excitation of in 30% (w/w) glycerol/water at different temperatures (increasing from bottom to top). Monitoring light at 488 nm, polarized parallel to the excitation pulse polarization. (b) Results of fitting a function “exponential decay plus constant” (see Experimental Section) to the transients in panel (temperature increases from right to left).
