Paper Abstract

We report the first resonance enhanced multiphoton ionization (REMPI) spectra of the boron-centered free radicals, BF, BCl, B2, BF2 and atomic boron. These spectra were observed between 300 and 380 nm by two photon resonances with previously unreported Rydberg states that reside between 58000 and 65600 cm-1. The radicals were produced by chain reactions of fluorine and chlorine atoms in a flow reactor and ion signals were analyzed by mass spectrometry. The REMPI spectra BF, BCl, B2, and BF2 originate from 3s and 4s Rydberg states. The spectrum of boron atoms arises from a new np Rydberg series and from a nf Rydberg series.
