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, D_J = 0.088(9) kHz, D_JK= -0.04(3) kHz, eQq_αα(Mn) = 68.00(4) MHz, C_bb(Mn) = -5.5(8) kHz. The distortion parameter D_J for CpMn(CO)₃ is compared to other D_J values for similar type transition metal complexes.
