摘要: Abstract The ν1 (CO stretching) and ν2 (CF bands of the FCO radical were observed with Doppler-limited resolution by an infrared diode laser spectrometer Zeeman source modulation. was generated a 60-Hz discharge in one following three gas mixtures: O2 + C2F4, CO SF6, all diluted He. spectra analyzed to determine rotational constants, centrifugal distortion spin-rotation interaction constants. band origins, 1861.6372(1) 1026.1283(1) cm−1 [with standard errors parentheses], which obtained, found agree well matrix data, 1857 1023 cm−1, respectively. assignment further supported observing F13CO, obtained from 13CO SF6. molecular structure force field are briefly discussed using constants spectra.
