Abstract

The v₇ parallel band of Fe(CO)₅ has been measured in the 620 cm^-1 region using high-resolution diode laser absorption spectroscopy in a free jet expansion. A comparison with simulated band profiles indicated a rotational temperature of between 2 and 3 K in the jet. At these temperatures the K-structure of the Q-branch is partly resolved. The following molecular parameters were obtained: v₀ = 619.95747(12) cm^-1, B₇ = 0.026743(2) cm^- ¹, A₇ = 0.030721(1) cm^-1. Approximate values of the quartic centrifugal distortion constants were also obtained from fitting the spectra. (C) 2000 Elsevier Science B.V.
