Abstract
The indium-amine radicals were produced by reactions of laser-vaporized metal atoms with methylamines seeded in helium gas and identified with time-of-flight mass spectrometry. Metal-ligand interactions of the positive ion and neutral species were probed using ZEKE spectroscopy. From the ZEKE spectra, ionization energies and metal-ligand stretching frequencies were determined for the three complexes, and bending frequencies were obtained for the monomethylamine and dimethylamine species. In comparison with $InNH_{3},^{a}$ these methylated complexes have lower ionization energies and stronger metal-ligand binding. $^{a}$G. K. Rothschopf, J. S. Perkins, S. Li and D. -S. Yang, J. Phys.
