Abstract
Vibrationally resolved spectra of the aluminum-phosphine and -arsine complexes were measured using ZEKE spectroscopy. The ZEKE spectrum of $Al-P(CH_{3})_{3}$ reveals the vibrational energy levels of low-frequency modes in the cationic and neutral species. These modes include the symmetric $Al^{+}-P$ stretching $(326 cm^{-1})$ and $Al^{+}-P-C$ bending $(76 cm^{-1})$ in the ion and the symmetric Al-P-C bending $(71 cm^{-1})$ in the neutral. The spectrum of $Al-As(CH_{3})_{3}$ displays a major progression associated with the $Al^{+}-As-C$ bending. Other transitions are also evident in the spectrum. Analysis is ongoing.
