Abstract

Summary: The laser irradiation at 193 nm of a gaseous mixture of carbon disulfide and ethene induces the copolymerization of both compounds and affords the chemical vapour deposition of a C/S/H polymer, the composition of which indicates the reaction between two to three CS~2~ molecules and one C~2~H~4~ molecule. Polymer structure is interpreted on the basis of X‐ray photoelectron and FT‐IR spectra as consisting of >CS, >CC<, CH~2~CH~2~, (CC)S~n~C~4 − n~, C(CS)S, S(CS)S, and CSSC configurations. The gas‐phase copolymerization of carbon disulfide and ethene represents the first example of such a reaction between carbon disulfide and a common monomer.

Scheme showing the expected reaction of excited CS~2~ molecules with other CS~2~ molecules to form dimers, which then react with another CS~2~ molecule or add to ethene.

The fluorescence of CFCl and CC12 excited by a tunable dye laser has been observed in the gas phase. The radiative lifetimes are 644 f 18 and 3810 i 300 ns respectively consistent with matrix results. The quenching rate ofCCl2 is greater than for CpCl and varies with the wavelength of excitation.

We present a new technique which can be employed for the efficient production of carbon clusters and fullerenes from the gas phase. It is based on the rapid transfer of the vibrational energy from CO\*-laser-excited SF6 to hydrocarbons. In a flow reactor, a low-pressure mixture of SF6 and &Hz is sub
