The infrared spectrum of the fluorocarboxyl radical, FCO2, was recorded at high resolution (0.0035 cm(-1)) in the 600-1400 cm(-1) region on a Bruker IFS 120 HR Fourier transform spectrometer of the University of Wuppertal. The analysis of the A-type v(2) band of FCO2 (CF stretching mode) centred at 970.208 cm(-1) was performed making use of the ground state parameters achieved by [L. Kolesnikova, J. Varga, H. Beckers, M. Simeckova, Z. Zelinger, L. Nova Striteska, P. Kania, H. Willner, and S.. Urban, J. Chem. Phys. 128, 224302/1 (2008)]. For the FCO2 radical, the v(2) transitions are, in principle, split into two spin-rotation subcomponents corresponding to J = N +/- 1/2. However the spin-rotation parameters in the 2(1) vibrational state have values similar to those of the ground state, and spin-rotation doublings are observable only for the weaker transitions involving medium K-a or K-c values in the P and R branches.
