Abstract

We report the first laser-based electronic spectroscopy of ground-state methylene radicals ( $X ~ 3 B 1$ ). Methylene was produced by reaction of fluorine atoms with methyl radicals and detected by mass-resolved, 3 + 1 REMPI between 370 and 440 nm. Resonances with the $B ~ 3$ $A 2$ (3d), $C ~$ (3d), $D ~$ (3d), and 4d $3 A 2$ Rydberg states of $C H 2$ and $C D 2$ have been identified between 70000 and $77500 c m −1$ above the ground state.
