 Title: VELOCITY MODULATION LASER SPECTROSCOPY OF VIBRATIONALLY EXCITED $CH^{+}$: DETERMINATION OF THE MOLECULAR POTENTIAL FUNCTION Creators: Gruebele, M.; Polak, M.; Saykally, R. J. Issue Date: 1986 Abstract: The lowest six vibrational hot bands of $CH^{+}$ have been measured in a helium/$C_{2}F_{6}$ discharge by velocity modulation laser spectroscopy. A total of 56 transitions has been fit to a Dunham expansion for $v=0-7$, yielding the parameters: $\omega_{e} = 1792.6654(18) cm^{-1}, B_{e} = 1.7204176(75) cm^{-1}. Y_{20} = -13.22968(54) cm^{-1}$, and $D_{0} = 62086(5) cm^{-1}$. The rotational temperature of $CH^{+}$ in the plasma is near $650^{\circ}K$ and the vibrational temperature is approximately $4500^{\circ}K$.
