Abstract

Microwave measurements of rotational transitions in cyclopentadienyl manganese tricarbonyl were made using a Flygare-Balle type pulsed beam Fourier transform microwave spectrometer operating in the 4-14 GHz range. Ninety-six hyperfine transitions were assigned for this prolate symmetric top for the rotational transitions J = 2→ 3, 3→4, 4→5, 5→6, and 6→7. Molecular constants obtained from the analysis of the spectrum are B = 828.0333(6) MHz, DJ = 0.088(9) kHz, DJK= -0.04(3) kHz, eQqαα(Mn) = 68.00(4) MHz, Cbb(Mn) = -5.5(8) kHz. The distortion parameter DJ for CpMn(CO)3 is compared to other DJ values for similar type transition metal complexes.
