First pulse-probe absorbance measurements of the hydrated electron at picosecond range and at elevated temperature. The decay of the hydrated electron, from room temperature up to 350 °C, is observed at 790 nm using laser triggered picosecond electron accelerator. The present work reports the first pulse-probe absorbance measurements of the hydrated electron at picosecond range and at elevated temperature. The decay of the hydrated electron, from room temperature up to 350 °C, is observed at 790 nm using a laser triggered picosecond electron accelerator. With increasing temperature, the decay of the hydrated electron becomes less and less pronounced. At 350 °C, almost a flat signal from 100 ps to 2.75 ns is observed, suggesting an efficient escape of hydrated electrons from spur reactions.
