β¦ Synopsis
Multidimensional infrared and Raman spectroscopy of liquids conducted using sequences of femtosecond pulses may be used to directly probe intramolecular and intermolecular nuclear motions. These techniques provide an additional insight into the nature of the nuclear spectral density observed in optical Kerr measurements. Photon echoes predicted in these systems are calculated and analyzed using multilevel coherences.

Optical dephasing of a cyanine dye chromophore in solution is investigated by time-gated photon echo spectroscopy in a three-pulse scattering geometry. The third-order polarization response is gated by up-conversion with a reference pulse in a nonlinear optical crystal. Time gating establishes two c
We present, for the first time, a study comparing phonon quench echoes in supercooled liquid argon with a normal mode analysis of the echoes. The phonon echoes are produced via molecular dynamics simulation. We model the echoes by considering a collection of harmonic oscillators whose frequency dist
The pressure dependence of the reoricntational correlation function for chiorofoti has been measured by analysis of the Rnman 3019 cm-' AI C-H stretching lincshnpc at 1, 1000, and 2000 bar and 23Β°C. These reorieniational correlation functions were obtained using the method of spectral Fourier deconv
The quadrupoiar spin echo from deuterons in ordered hydrocarbon systems is shown to provide a much more reliable spectrum than the conventional free induction decay Fourier transform. Spectrometer dead time is eliminatsd, phase correction uncertainties removed and signzllnoise enhanced.
