Abstract
To date, carbon-selenium clusters have received little attention from both experiment and quantum-chemistry.
Recent high-resolution infrared survey scans of the ablation products from carbon-selenium targets in the 5$\mu$m regime
have revealed two bands previously not observed in the gas phase.
On the basis of comparison with high-level quantum-chemical calculations performed at the CCSD(T) level of theory
these bands are attributed to the linear SeC$_3$Se and C$_3$Se chains. Following the microwave detection of
diatomic CSe some 45 years ago\footnote{J. McGurk, H. L. Tigelaar, S. L. Rock, C. L. Norris, and W. H. Flygare, J. Chem. Phys. 58, 1420 (1973).} the present work marks the first high-resolution detection of polycarbon selenium clusters.
