Abstract
The origin of the strong CO Cameron band emission in the Red Rectangle is i nvestigated. From a comparison of laboratory spectroscopic data and astrono mical observations in combination with chemical modelling, it is concluded that the Cameron band emission of CO originates from the dissociative recom bination of HCO+, and its intensity provides a measure of the product of th e density of HCO+ ions and the electron density, integrated along the line of sight.
