Abstract

The subtraction of collision-induced backgrounds from allowed Raman bands can often pose severe problems in conventional Raman spectroscopy as the deconvolution procedures employed frequently rely on theoretical assumptions in respect to the collision-induced line shape. It is shown here that the use of high-dynamic picosecond nonlinear optical techniques in the time domain can give direct access to Raman line widths and shapes even when the spectrum is dominated by collision-induced processes.
