When a Ne:SiF4 mixture is codeposited at approximately 5 K with a beam of excited neon atoms, the infrared spectrum of the resulting deposit includes absorptions of SiF3, together with new absorptions which have been assigned to SiF+3 and SiF-3. The results of ab initio calculations of the structure and ground-state vibrational fundamentals of these two ion species are presented, and support the proposed assignments.
