High-resolution FTIR study of the CO stretching band v(4) of the fluoroformyloxyl radical, FCO2
Original language description
The v(4) fundamental band (CO2 antisymmetric stretching mode) of the FCO2 radical in the ground electronic state (X) over bar B-2(2) has been recorded by Fourier-transform infrared spectroscopy at an effective resolution of 0.003 cm(-1) between 1040 and1130 cm(-1). FCO2 was generated by vacuum flash pyrolysis at about 350 degrees C of FC(O)OO(O)CF. More than 3300 ro-vibrational transitions have been assigned, which involved levels with N' up to 56 and K-a' up to 38. The observed Doppler-broadened spectrum was analyzed to yield accurate values of the band origin (1094.142210(27)cm(-1), one standard error in parentheses), the rotational constants, the quartic centrifugal distortion constants and electron spin-rotation interaction parameters in the v(4)=1 state. Large variations of the centrifugal distortion parameters Delta(kappa)(+26%), Delta(N kappa) (-1463%) and delta(kappa)(-10%) upon excitation of the v(4) vibration have been observed.
