High-resolution infrared study of carbon-rich clusters C3X and XC3X (X = Se, Te) — Sven Thorwirth1, •Thomas Salomon1, John B.

To date, carbon-rich clusters harboring heavy elements have received little attention from both experiment and quantum chemistry. Recent high-resolution infrared survey scans of laser ablation products from carbon-selenium and carbon-tellurium targets in the 5µm wavelength regime have revealed several vibration-rotation bands not observed previously. On the basis of comparison with results from density-functional theory (DFT) calculations and high-level quantum-chemical calculations performed at the CCSD(T) level of theory these bands are attributed to new linear chains of the form C3X and XC3X with X being either Se or Te.
