    • Abstract:
      Knowledge of elementary relaxation processes in small molecules and proteins motivates the extension of two-dimensional photon echo (2DPE) spectroscopy further into the UV wavelength range. Here, we describe our development of a four-wave mixing spectrometer employing 200 nm laser pulses. Filamentation of laser beams in both air and argon yields 200 nm pulses with 60 fs durations. These 200 nm pulses are used to probe dynamics initiated at 267 nm in transient grating and 2DPE experiments conducted on adenosine. This study demonstrates that these femtosecond spectroscopies may indeed be carried out at the shortest wavelengths feasible in aqueous solutions.
