Recent high-resolution infrared survey scans of laser ablation products from carbon-tellurium targets in the 5 μm wavelength regime show vibration-rotation bands not observed previously. On the basis of comparison with results from density-functional theory and high-level quantum-chemical calculations performed at the CCSD(T) level of theory these bands are attributed to two new linear chains, C<sub>3</sub>Te and TeC<sub>3</sub>Te.  The poster will present these bands and reports the most recent spectroscopic parameters obtained by CCSD(T) with consideration of relativistic effects.
