45. 2+, Coumarin 480 was pumped by the third harmonic of the Nd:YAG to yield 25-fs pulses centered at 475 nm (full-width at half-maximum of 20 nm). A small portion of this pulse was redirected into an optical fiber to generate a ∼10-fs probe pulse following recompression with prisms and gratings. Signals were modulated at 80 Hz, and data were collected with the use of a lock-in amplifier. Linearity of the data was confirmed using neutral density filters; the maximum observed change in transmission was typically 8%. Thirty spectra were collected at each time delay, and this cycle was repeated 20 times to afford the signal-averaged data.

51. It is difficult to assess vibrational relaxation dynamics given the broad, somewhat featureless nature of electronic absorption spectra. However, because charge-transfer spectra are particularly sensitive to changes in molecular structure, it is reasonable to assume that most of the structural rearrangement in the system is complete by Δt = 300 fs.
