Emission spectra of C<SUB>2</SUB>H<SUB>2</SUB> and C<SUB>2</SUB>D<SUB>2</SUB> excited by collisions with electrons of 7–20 eV show a broad and diffuse band in the 240–400 nm region and this band was assigned to the S<SUB>1</SUB>(lower vibrational levels)–S<SUB>0</SUB> transition of acetylene on the basis of its .wavelength, excitation function (threshold: 5.5 eV) and lifetime (323±30 ns). Their emission cross sections are on the order of 10<SUP>−19</SUP> cm<SUP>2</SUP>. Among intense fragment emissions at higher electron energies, band of C<SUB>2</SUB>H has also been observed and its lifetime is 3.9±0.8 μs.
