โœฆ Synopsis

The absorption spectrum of a microwave discharge (2450 MHz) in flowing helium with traces of SiF 4 has been recorded on the SA61 beam line of SUPERACO between 2000 and 500 ร…. Two new ionization energies have been observed at 15.12 and 17.27 eV corresponding, respectively, to the A 1 โŒธ and B 1 โŒบ ฯฉ states of SiF ฯฉ . The A 1 โŒธ 4 X 1 โŒบ ฯฉ transition of the ion has been identified for the first time on high-resolution spectra obtained in 1992 with the 35-foot Eagle spectrograph in Meudon.

In the range 110-200 nm the absorption features of Si#& closely resemble those of SiCl, and the peaks observed are tentatively assigned to the Rydberg transitions of a Cl lone-pair electron. Two diffuse bands in the SiF,CH3 absorption are also assigned to Rydberg excitations. The spectrum of GeF., s

The mlcrowave spectra of SiF$ZN and SiF,NC have been mcasurcd in gaseous mixtures generated in situ from the reactlon of SiF,X (X=1, Fir) with AgCN. The species have been identified by complete structural determination via detailed isotopic substitution. The zero-point average structure ofSiF,CN was
