Vibrational Spectra of IF7and ReF7

摘要

Raman spectra of IF7and ReF7have been observed for the first time in the vapor state. Infrared spectra of the vapors have also been rehyphen;examined. Earlier difficulties regarding possible coincidences in the IF7spectra have been removed. The data suggest that both molecules belong to symmetry groupD5h, although there are some significant as yet unexplained differences between them.
