  abstract = {<p>Hydrogen-capped polyynes have been synthesized by 800&nbsp;nm femtosecond photolysis of acetone molecules. Four bands appearing in the 1800–2200&nbsp;cm<sup>−1</sup>&nbsp;range of surface enhanced Raman spectra show a mixture of polyynes with variable chain lengths in the irradiated acetone. The shortest hydrogen-terminated chain is found to be C<sub>6</sub>H<sub>2</sub>. The presence of charged carbon dimer, monomer&nbsp;C2+, C<sup>+</sup>&nbsp;and double charged C<sup>2+</sup>&nbsp;has been confirmed by time-of-flight mass spectroscopy. These ions are generated as irradiation products of stepwise dissociation of acetone and further act as building blocks in the synthesis of polyynes.</p>
