Abstract
The $\nu_{2}$, bending, fundamental band of $CO_{2}^{+}$ has been detected by diode laser absorption spectroscopy at wavelengths between $17.5 \mu m$ and $22.2 \mu m$. The combined effects of vibronic and spin orbit coupling split the spectrum into several well separated component bands and information on all of the vibronic components associated with $v_{2} = 0$ and 1 has been obtained. Analysis of the spectra has yielded precise estimates of the rotational, A-doubling and spin uncoupling parameters while the vibronic splittings give information on the spin orbit coupling and the vibronic potential functions. $^{\ast}$Research carried out at Brookhaven National Laboratory was performed under contract DE-AC02-76CH00016 with the U. S. Department of Energy and supported by its Division of Chemical Sciences.
