Abstract
The microwave spectra of two isomers of cyclopentadiene-1-carbonitrile generated by the pyrolysis of 1H-benzotriazole have been observed in the frequency range from 8.0 to 40.0 GHz. The rotational constants (MHz) have been determined as A=8353.7(9), B=1904.24(1), and C=1565.38(1) for 1,3-cyclopentadiene-1-carbonitrile, and A=8235.0(13), B=1902.07(2), and C=1559.67(2) for 1,4-cyclopentadiene-1-carbonitrile. The dipole moments (Debye) obtained are μa=4.15(15), μb=0.27(3), and μtotal=4.16(17) for 1,3-cyclopentadiene-1-carbonitrile and μa=4.36(25), μb=0.77(10), and μtotal=4.42(35) for 1,4-cyclopentadiene-1-carbonitrile.
