Abstract : Investigation of the spectrum of combined diffusion of gaseous NF3 was conducted with the aid of a multipasstype vessel. Two of the bands are wide ones: nu4 = 495/cm and nu3 = 911/cm, confirming their designation to degenerated (incompletely symmetrical) oscillations of the NF3 molecule. Two other bands (nu1 = 1033/cm and nu2 = 646/cm) appear to be sharp ones and belong to fully symmetrical oscillations of the NF3 molecule. The frequency values observed are in good agreement with values found earlier from infrared absorption spectra (M.K. Wilson and S. R. Polo, J. Chen. Phys. 20:1716 (1952) and E. L. Pace and L. Pierce, J. Chene. Phys. 23:1248 (1955)).
