Picosecond transient Raman spectroscopy of excited state dynamics.
01 January 1986
An apparatus is described which generates very sensitive picosecond transient Raman spectra with 5 ps time resolution. The fast repetition rate high peak power picosecond pulses necessary to detect weak Raman scattering were obtained using a copper vapor laser to amplify sync pumped dye laser pulses. Transient vibrational spectra obtained by this technique have been used to investigate the excited state photophysics of substituted diphenylethylenes.
