Transient technique — A technique whose response is time dependent and whose time dependence is of primary interest, e.g., -> chronoamperometry, -> cyclic voltammetry (where current is the transient), -> chronopotentiometry and -> coulostatic techniques (where voltage is the transient). A transient technique contrasts with steady-state techniques where the response is time independent [i]. Some good examples are cyclic voltammetry [i, ii] (fast scan cyclic voltammetry), the indirect-laser-induced-temperature-jump (ILIT) method [iii], coulostatics [i]. The faster the transient technique, the more susceptible it is to distortion by -> adsorption of the redox moiety.

An adaptation of the temperature-jump method, named indirect laser-induced temperature jump [29], was used in studies of distance dependence of electron transfer at electrodes. A pulsed Nd YAG laser was used to cause a sudden (<5 ns) change in temperature (<5 K) at an electrode/electrolyte interface. The increase in temperature causes a change in the open-circuit potential. The relaxation step is a function of the dissipation of thermal energy and the rate of electron transfer between the electrode and its redox partners.

The behavior of interfacial water molecules on platinmn single-crystal electrodes, under electrochemical conditions, has been characterized for the first time by means of the laser-induced temperature jump method. The fundamentals of this method and the proposed interpretation of the experimental results will be described in Section V.l and V.2. Then, recent results on the three platinum basal planes will be discussed in Section V.3. Afterwards, the application of this technique to Pt(lll) stepped surfaces will be explained in Section V.4. And finally, results on the effect of the chemical modification of the surface composition of Pt(l 11) by adatom deposition will be presented in Section V.5.

The following Sections will summarize some recent results on the application of the laser-induced temperature jump method to characterize the net orientation of interfacial water on platinum single-crystal electrodes, under electrochemical conditions. 

The apphcation of the laser-induced temperature jump method requires that the only effect of the laser pulses is the heating of the electrode surface, resulting in a sudden temperature change at the interphase. In this regard, the laser ptrlses employed in the experiments described in Section V (wavelength of 532 run, drrration of...

One way to effect a rapid change in the interfacial temperature is by impinging a pulsed laser beam directly onto the electrode [66 71] we will refer to this method as the direct laser-induced temperature-jump method (DLIT). DLIT has several fundamental problems ...
