Absolute intensities of infrared-active fundamentals and combination bands of gaseous PuF6 and NpF6

Article abstract of DOI:10.1063/1.451564

Results are presented for the absolute integrated molar absorption coefhcients of the infrared-active fundamental and binary combination bands of PuF6 and of NpF6 between 1400 and 450 cm^-1.The low resolution band contours of the combination bands ν₁+ν₃, ν₂+ν₃, ν₃+ν₅, ν₂+ν₆, and ν₂+ν₄ are discussed.From band center positions, the six harmonic wave numbers were obtained and Coriolis constant ζ_i (i = 3, 4, 5, and 6 ) estimated.For PuF6, the six normal mode vibrations appear to group into one local mode stretching at a mean value of 589+/-50 cm^-1 and one local mode bending at 195+/-5 cm^-1.The role of the heavy central atom and the magnitudes of the vibrational force constants are discussed in comparison with UF6.The measured intensity for ν₃ is discussed in comparison with previously predicted values.
