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
已在 8.0 至 40.0 GHz 的频率范围内观察到由 1H-苯并三唑热解产生的环戊二烯-1-腈的两种异构体的微波光谱。对于 1,3-环戊二烯-1-腈,旋转常数 (MHz) 已确定为 A=8353.7(9)、B=1904.24(1) 和 C=1565.38(1),并且 A=8235.0(13),对于 1,4-环戊二烯-1-腈,B=1902.07(2) 和 C=1559.67(2)。1,3-环戊二烯-1-腈的偶极矩(Debye)为μa=4.15(15)、μb=0.27(3)、μtotal=4.16(17),μa=4.36(25)、μb=0.77 (10),对于 1,4-环戊二烯-1-腈,μtotal=4.42(35)。
