The goal of the work in this paper is the development of methods of IR laser spectroscopy that can initiate and probe chemical change in zeolites across timescales of nanoseconds to seconds. Pulsed-laser infrared (IR) absorption spectroscopy allows vibrational spectra to be recorded with a time resolution as small as femtoseconds, allowing the study of dynamical processes such as bond breaking, structural rearrangements and molecular diffusion. Dynamical processes are initiated by pulsed-laser excitation and monitored with synchronised, timeresolved spectroscopic probing of the resulting molecular changes. It is common to initiate chemistry by excitation of electronic absorption bands in the UV / visible part of the spectrum, however using a laser to simply heat a sample (temperature-jump, or T-jump spectroscopy) enables thermally activated processes to be studied over multiple decades in time from picoseconds to milliseconds. The time for a sample to fall back to its initial temperature is dependent on its thermal properties. Starting with ps-ns heating pulses, elevated temperatures in the millisecond range are possible for solution phase samples, allowing non-equilibrium structural dynamics to be observed, with further timescales accessible through more sophisticated laser heater sources. While IR laser T-jump methods have seen application to solution-phase chemistry particularly in the field of biomolecule dynamics, time resolved IR T-Jump investigations of heterogeneous catalysts are absent in the literature. The use of CW lasers to simply heat zeolites has been explored, but the ability to synchronously collect timeresolved spectra on the evolution of the sample was not implemented. Similarly, picosecond pulsed-IR investigations of zeolites have demonstrated how the relaxation of excited O-H and O-D vibrations induces heating of the zeolite framework, and quantified the resulting temperature transients, but only considered the heating as an unwanted background to the relaxation behaviour on picosecond timeframes. The ability to heat solid materials and monitor their evolution from nanoseconds to seconds with time-resolved IR remains unexplored. In this paper we describe experiments to do exactly this with an approach of pulsed-laser T-jumping and time-resolved IR probing for investigating laser heating in a hydrated commercial H-ZSM-5 zeolite powder. Acid zeolites possess strongly absorbing O-H vibrations at around 3600 cm -1 . These are ideal modes to optically pump and induce the required laser heating. To this end, a Nd:YAG-pumped Optical Parametric Oscillator (OPO) operating in the mid-IR was used. Time resolved multiple probe spectroscopy (TRMPS) with a broadband IR probe was able to access dynamical timescales from nanoseconds to seconds in a single measurement, representing a new approach to investigate fast temperaturerelated phenomena in zeolites. We demonstrate time-resolved IR experiments performed in transmission with compressed (pelleted) solid zeolite samples under conditions of controlled gas flow and elevated sample temperature. Classical heat transfer simulations of the pumped sample are used to provide insight into the spatial distribution and temporal evolution of heat. We experimentally determine the timedependent temperature of the laser heated zeolite sample relative to its starting conditions by using the established approach of identifying temperature-dependant modes in the IR spectrum for use as spectroscopic 'thermometers'. For zeolites, by partially deuterating the samples and probing spectral changes in the 2500-3000 cm -1 spectral range, we find that the narrow, temperature-sensitive stretch band of deuterated, intrinsic silanol groups makes an excellent 'thermometer'. Optical scattering from the bright T-Jump laser pulse can easily saturate the IR detector used to monitor the probe transmission. Partial deuteration allows (OH) stretch mode pumping and probing in the separate spectral region of mainly (OD) stretch modes.
