Abstract

The rotationally resolved spectrum of the v₁₁ (E′) fundamental band of Fe(CO)₅ at 649 cm^-1 has been measured in a supersonic jet using infrared diode laser absorption spectroscopy. Adopting a ground state A rotational constant of 0.030 75 cm^-1, calculated from the electron diffraction structure, the following rotational constants were determined; A₁₁ = 0.030 71(3) cm^-1, B₀ = 0.026 82(11) cm^-1 and B₁₁ = 0.02683(10) cm^-1. The B rotational constants are in close agreement with recent ab initio calculations. The band origin is 649.078 9(22) cm^-1 and the Coriolis coupling constant ζ₁₁ = +.838 8(10).
