Abstract: The dynamics of intramolecular vibrational-energy redistribution from an initially excited mode ν₁ (the acetylene-type H-C bond) to the other modes of the H-C≡C-Si(CH₃)₃ molecule was studied experimentally. Probing was performed by spontaneous anti-Stokes Raman scattering. The measured deexcitation time of ν₁ was 128±10 ps.
