Schematic of the dual time-resolved T-jump fluorescence and IR spectrometer. An AOM pulse picker reduces the repetition rate of the 50 Hz pulsed Q-switched Ho:YAG laser and produces the 2.09 μm pump radiation that is the source for both the IR and fluorescence T-jump. By using multiple quantum cascade lasers, the total frequency range spanned by the IR system is 1000–2250 cm−1. Fluorescence is excited using a mode-locked, frequency tripled Ti:Sapphire laser and emission is collected with a photomultiplier tube and an appropriate band pass filter.
