✦ Synopsis

We report the visible photofragmentation spectroscopy of M&CO:. Two molecular absorption bands, leading to both Mg+ and M& daughter fragments, are observed. In the red band (ranging from ~430 to ~725 nm), both Mg+ and Mg: action spectra consist of a progression of discrete vibrational resonances, superimposed on a continuum background. In the green baud ( x 530 to z 568 nm), the absorption profile consists of a structureless continuum, void of resonance features. We assign the red band as 1 ?II+-1 *Z+, and the green band as 2 'Z++ 1 * Z +, in a linear MgzCO: complex. The fragmentation dynamics are, however, not understood.
