Notes:
A Fourier transform infrared study has resulted in the first observation of a vibrational spectrum of the nonplanar H2SiCCH radical produced by trapping the products of the vacuum ultraviolet photolysis of a mixture of SiH4 silane, and C2H2 acetylene, in an Ar matrix at ∼10 K. Two vibrational fundamentals have been observed, the ν3(a′), silicon–carbon stretching mode at 2055.6 cm−1 and the ν4(a′), hydrogen–silicon bending mode at 926.8 cm−1. The vibrational frequencies, relative intensities, and extensive measurements of D and 13C isotopic shifts are all in good agreement with the values predicted by new density functional theory calculations. © 1998 American Institute of Physics.
