A note on the absorption spectra of bromine trifluoride, iodine pentafluoride and cyanogen fluoride

Structural chemistry of the interhalogen compounds

“…Considerable work has been done on the structure of iodine pentafluoride in recent years. It shows a continuous absorption spectrum in the visible range, indicating no vibrational structure (25). Its electron diffraction pattern indicates that it is not a trigonal bipyramid (15) but it is difficult to determine its structure because of the relatively low scattering power of fluorine in X-ray diffraction patterns.…”
