Abstract
The gas-phase electronic absorption spectra of several new carbon molecular systems could be observed in the laboratory allowing a direct comparison with astronomical DIB data. These include the non-linear carbon chains, C$_n$H$_4^+$ n=4,6,8, C$_5$H$_5$ isomers which absorb near the 4429 DIB, and large cyclic systems such as C$_{18}$, all with absorbtions in the visible.
