Revisiting The Renner–Teller Effect In The X ̃2Π State Of Ccn: Pulsed Discharge-Supersonic Jet Single Vibronic Level Emission Spectroscopy, Lloyd Godfrey Muzangwa, Scott Reid

Chemistry Faculty Research and Publications

The CCN radical is a prototypical system for study of the Renner–Teller effect in its degenerate X ̃²Π ground state, with a number of experimental and theoretical studies carried out over the past 50 years. Most experimental studies have focused on the low-lying vibrational structure as observed in the high-resolution spectra of hot bands, or in emission. In this work, we have used pulsed-discharge supersonic-jet single vibronic level (SVL) emission spectroscopy from selected levels of the Ã²Δ state to probe the vibronic structure of X ̃²Π up to ∼6000 cm⁻¹ above the …
