Abstract
The microwave spectrum of pentafluorobenzonitrile has been reinvestigated in the light of subsequent studies of many fluorosubstituted benzenes. The rotational and centrifugal distortion constants obtained (in MHz) are $\bar{A} = 1029.027(24), \bar{B}= 759.956(14), \bar{C} = 437.554(14), \Delta_{J} = -0/000096(13), \Delta_{JK} =0.00070(5), \Delta_{K}= -0.00005(11), \delta_{J} = -0.000016(7)$ and $\delta_{K} = -0.00044(3)$. The structural distortion of the benzene ring is on the expected lines with other fluorosubstituted benzene molecules.
