Thermally induced solution stirring can cause periodic signal fluctuations which can be the sensitivity limiting factor in thermal lens spectroscopy with a chopped pump laser. Pump and probe laser fluctuations are shown to be random, while thermal lens signals are shown to have a small periodic component caused by stirring. The problem is serious in dilute solutions because of the high solvent background absorbance.

The Cross

The dynamics of iodide-uracil-water (I<sup>−</sup>·U·H<sub>2</sub>O) clusters following π-π* excitation of the nucleobase are probed using time-resolved photoelectron spectroscopy (TRPES). Photoexcitation of this cluster at 4.77 eV results in electron transfer from the iodide moiety to the uracil, creating a valence-bound (VB) anion within the cross-correlation of the pump and probe laser pulses. This species can decay by a number of channels, including autodetachment and dissociation to I<sup>−</sup> or larger anion fragments. Comparison of the energetics of the photoexcited cluster and its decay dynamics with those of the bare iodide-uracil (I<sup>−</sup>·U) complex provide a sensitive probe of the effects of microhydration on these species. The results are also compared with TRPES experiments on I<sup>−</sup>·U·H<sub>2</sub>O at lower pump photon energies, where both the initial photoinduced dynamics and the decay of the photoexcited cluster are qualitatively different.

Laser-induced grating spectroscopy (LIGS) is an experimental method in which two pulsed laser beams and a continuous-wave laser beam have to be superimposed under well-defined angles to generate a coherent signal beam. In this Note, the possible effects of different forms of misalignment are examined. This includes the overlap of the pump lasers as well as the influence of the probe laser alignment on the temporal profile of the signal.
