Abstract

The microwave spectrum of cyclopropanecarboxylic acid has been measured in the 5-15 GHz region using a Flygare-Balle type, pulsed-beam Fourier-transform microwave spectrometer. These lower-frequency measurements are at a much higher resolution then the previous waveguide studies. The experimental rotational constants obtained in this study were A = 7625.0432(17) MHz, B = 2724.7672(8) MHz, and C = 2382.0755(5) MHz. The centrifugal distortion constants determined were Δ_J = 0.4010(25) kHz, Δ_JK = 3.04(17) kHz, Δ_J = 0.0434(72) kHz, and Δ_K = -11.32(24) kHz.
