Abstract

The microwave spectrum was measured for ferrocenecarboxylic acid in the 4.8–9.8 GHz range using a pulsed-beam Fourier transform microwave spectrometer. 27 transitions were measured and assigned, which include a-, b-, and c-type rotational transitions. From the measured transitions, the rotational and centrifugal distortion constants were determined. The values determined are A = 1138.0162(13) MHz, B = 653.81796(54) MHz, C = 559.83162(47) MHz, D_J = 0.0675(52) kHz, D_JK = −0.157(36) kHz, D_K = 0.193(47) kHz, and d_J = 0.0194(22) kHz. MP2 and B3LYP gas phase structure optimizations were performed with the aug-cc-pVTZ basis and the B3LYP method yielded rotational constants that were in far better agreement with the experimentally determined values than the MP2 results.
