Abstract

The ν₃ fundamental band of CO₂⁺ has been observed with infrared diode laser spectroscopy, while modulating a hollow cathode discharge in CO₂ by a magnetic field. The band origin has been determined to be 1423.0821(8) cm⁻¹. This anomalously low value has been explained in terms of a vibronic interaction between X̃ ²Π_g and Ã ²Π_u through the ν₃ vibration, as in the case of BO₂.
