摘要：

We demonstrate and characterize an apparatus for transient infrared spectroscopy with a 5-ps resolution. A visible pump and narrow-band mid-infrared probe are both derived from a source that is based on a pulsed Nd:YAG regenerative amplifier that operates at 540 Hz. We measure transient spectra in the range 1770-2250 cm-1 with a 1-cm-1 resolution and sensitivity to absorbance changes less than or equal to 1 x 10(-3). As an example, we present results from experiments to study ligand photodissociation from carboxymyoglobin in D2O.
