This work is concerned with the advancement of instrumentation used for the structural investigation of ultrafast (10;Initial studies involve the acquisition of picosecond transient Raman spectra of S;Additional investigations involve the cis/trans isomerization of cyanine dyes. To aid in the assignments of vibrational bands observed in the excited state transient Raman spectra of these dyes, the infrared and spontaneous Raman ground state spectra of the cyanine dye 3,3... |
