The three title compounds are found to form stable negatively charged states. Si2H2 exhibits two anion states (2A s and 2Bs) corresponding to adiabatic electron affinities (EAs) of 1.76 and 1.23 eV. Si2H3 has two stable anion states ( tA and 3A) associated with EAs of 2.20 and I. 17 eV. Disilene sho
Evaporation of silicon and consecutive cocondensation of the isolation of three new C 2 H 4 Si isomers [apart from the known silacyclopropene (7) and silylacetylene (8)], namely generated atoms with acetylene or ethylene in an argon matrix turnes out to be a new access to C 2 H 2 Si and C 2 H 4 Si s
The microwave rotational spectra of two singlet chains H 2 CCSi and H 2 C 4 Si, have been observed in a pulsed supersonic molecular beam by Fourier transform microwave spectroscopy. Following detection of the singly substituted rare isotopic species and D 2 CCSi, an experimental structure (r 0 ) has

Temperature dependenrrs of cqniti& rium constants were obtained by a standard statistical-thermodynamic treatment for which all necessary molecular tortstants were generated by the ab initio SCF calculations of double zeta qual
The Rydberg states of the acetylene clusters ( C2H2)a and (C,H,), have been resolved by the technique of twophoton resonant ionization spectroscopy in the energy region of the monomer gerade Rydberg states. The stability of these cluster Rydberg states has been found to be vibrational mode dependent
