Abstract

The lowest six vibrational hot bands of CF⁺ have been measured in a helium/C₂F₆ discharge by velocity modulation laser spectroscopy. A total of 56 transitions has been fitted to Dunham expansion for v = 0-7, yielding the parameters: ω_e = 1792.6654(18) cm^-1B_e = 1.7204176(75) cm^-1, Y₂₀, = -13.22968(54) cm^-1, and D₀ = 62086(30) cm^-1. The rotational temperature of CF⁺ in the plasma is near 650 K and the vibrational temperature is approximately 5200 K.
