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: ωe = 1792.6654(18) cm-1Be = 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.
