	abstract = {The ground state vibrational energy levels of jet-cooled SiCH and SiCD have been studied by a combination of laser-induced fluorescence and wavelength-resolved fluorescence techniques. The radicals were produced by a pulsed electric discharge at the exit of a supersonic expansion using tetramethylsilane or methyltrichlorosilane as the precursor. Emission spectra have been obtained by pumping both perpendicular and parallel (vibronically induced) bands, providing complementary information on the Si-C stretching and Si-C-H bending modes. Ground state energy levels up to 4000 cm(-1) have been assigned and fitted using a vibrational Hamiltonian that incorporates Renner-Teller, spin-orbit, vibrational anharmonicity, and Fermi resonance interactions. The validity of the derived parameters has been tested using the isotope relations. (C) 2001 American Institute of Physics.},

	abstract = {The (A) over tilde (2)Sigma(+)-X (2)Pi(i) transition of jet-cooled silicon methylidyne, SiCH, has been recorded by laser-induced fluorescence in the 850-600 nm region. The radical was produced in an electric discharge using tetramethylsilane as the precursor. Fifteen cold bands of SiCH and 16 bands of SiCD have been assigned vibrationally, giving the upper state frequencies as v(2)({\textquoteright})=715/558 cm(-1) and v(3)({\textquoteright})=1168/1127 cm(-1) for SiCH/SiCD. Rotational analysis of the 0(0)(0) and 3(0)(3) bands for each isotopomer has given the following molecular structures: r(0)({\textquoteright})(Si-C)=1.692 52(8), r(0)({\textquoteright})(C-H)=1.0677(4), r(0)({\textquoteright})(Si-C)=1.6118(1), and r(0)({\textquoteright})(C-H)=1.0625(5) Angstrom. The silicon-carbon bond length in the X (2)Pi ground state of SiCH (electron configuration ...sigma(2)pi(3)) is typical for a Si=C double bond; in the (A) over tilde (2)Sigma(+) excited state (...sigma(1)pi(4)) it corresponds to a triple bond. This work provides the first experimental measurement of the length of the carbon-silicon triple bond. (C) 2000 American Institute of Physics. [S0021-9606(00)00508-0].},
