Vibrational Spectra of IOF5, OsOF5, and ReOF5

Abstract

Raman spectra of IOF5, OsOF5, and ReOF5, and the infrared spectra of OsOF5 and ReOF5 are presented, all for the gaseous state. Complete assignments of fundamental frequencies are made, and these confirm the expected C4ν symmetry. Fundamental frequencies in cm−1 in the order, 4a1, 2b1, b2, and 4e, are: for IOF5, 927.0, 680.4, 640.2, 362.9, 647, 307, ∼ 330, 710.3, 372.2, 343, and 204.8; for OsOF5, 962.6, 716.4, 644, 280.5, 644, 210, 332, 700.6, 263, 367, and 164; and for ReOF5, 989.8, 738.6, 643, 309, 652, 234, 334, 713.0, 260, 365, and 125 cm−1.
