Abstract

We measured picosecond transient Raman spectra of Si trans-stilbene in hexane and Si diphenylbutadiene in THF. We observed 18 vibrational modes in the trans-stilbene spectra and 9 modes in the diphenylbutadiene spectra. The band positions and band shapes of the transient Raman spectra suggest a distribution of molecular conformers in Si having different single and double bond strengths. The band intensities in the trans-stilbene spectra suggest a redistribution of electron density in Sn that is concentrated in the olefinic region and in the ortho and meta region of the phenyl rings. We also measured the low wavenumber Stokes and anti-Stokes spectra in trans-stilbene.
