MATRIX-ISOLATION STUDY OF THE INTERACTION OF EXCITED NEON ATOMS WITH BF3 - INFRARED-SPECTRA OF BF2+, BF3+ AND BF3-

When a Ne:BF3 sample is codeposited at approximately 5 K with a beam of neon atoms that have been excited in a microwave discharge, the infrared spectrum of the resulting solid deposit shows prominent absorptions of BF 2. All three vibrational fundamentals and the v1+v 3 combination band of BF2 isolated in solid neon are identified, and a normal coordinate analysis is conducted. In addition, infrared absorptions of the BF3+, BF2+, and BF3- molecular ions are assigned, and the processes which occur when the solid deposit is exposed to visible and ultraviolet radiation are considered.
