RYDBERG STATE SPECTROSCOPY OF BORON HYDRIDE RADICALS.

Abstract

Ionization dtected electronic absorption spectra of radical boron hydrides will be reported. $BH_{x}$ radicals are produced by ArF (193 nm) photolysis of $B_{2}H_{6}$ in a supersonic pulsed-jet. Ions are mass-resolved and detected using a time-of-flight mass spectrometer. Various Rydberg states of BH and $BH_{2}$ will be discussed.
