The high-resolution, jet-cooled infrared spectrum of pentafluoroethane

► The jet-cooled, high-resolution IR spectrum of C2HF5 has been recorded between 1100 and 1325 cm−1. ► Transitions in five fundamental vibrations have been assigned and fit to a Watson Hamiltonian. ► At 10 K, these five bands do not show any significant perturbations for the low J and K transitions. ► Joint fits with previous work were attempted for the ν4 and ν13, successfully in the former case. ► Rotational structure in the ν5 and ν14 bands has been assigned for the first time.
