The microwave spectrum of cyclopropane(1,1)dicarbonitrile has been studied between 18 and 40 GHz by modulated microwave double resonance spectroscopy. The molecule is a b-type asymmetric rotor with κ≈-0.20. Lines with J values up to 27 have been fit to a quartic Hamiltonian. Rotational constants obtained from this fit include A=3779.65 MHz, B=2549.21 MHz, C=1726.75 MHz. The CC bond opposite the substituents has been estimated from the planar moment to be 1.485±0.01 Å.
