Our investigation of NiCH 2 + represents the first reported spectroscopic study of this molecule. A spectroscopic threshold is observed for each of the three systems. In addition to imposing strict upper limits on the M +-CH 2 bond strengths, these results further the discussion concerning the interpretation of spectroscopic thresholds as thermodynamic limits. The measured upper limits are: D°0(Fe +-CH 2) e 342 (2 kJ/mol, D°0(Co +-CH 2) e 331 (2 kJ/ mol, and D°0(Ni +-CH 2) e 295 (5 kJ/mol. Three distinct, 2-nm-wide peaks are observed in the photofragment spectrum of CoCH 2 + , but the spectra lack sharp structure above threshold.
