Abstract

Fourier-transform infrared spectroscopy of trifluorovinyl radical, C₂F₃, in an argon matrix has been investigated. A novel dc discharge-pulsed supersonic expansion produced high concentrations of the C₂F₃ radical from C₂F₃I/Ar, C₂F₃Br/Ar and C₂F₄/Ar precursors. The fourth harmonic of a YAG laser was also used to generate the C₂F₃ radical. Four vibrational frequencies have been found: v₁ = 1780.4, v₂ = 1282.4, v₃ = 1216.9 and v₄ = 900.0 cm^-1. All of the vibrational frequencies are in good agreement with previous theoretical calculations; v₂ and v₃ are in good agreement with previous gas phase IR laser investigations.
