The microwave spectra of two isotopes of selenium tetrafluoride, SeF4, have been recorded between 8000 and 40 000 MHz. The rotational constants that predict the spectra are: A = 5359.935, B = 3395.079, C = 2780.431 MHz for 80SeF4 and A = 5370.448, B = 3399.281, C = 2780.416 MHz for 78SeF4.The structural parameters obtained from these constants are: rSeF(E) = 1.6821 Å, rSeF(A) = 1.7713 Å, F(E)SeF(E) = 100.55° and F(A)SeF(A) = 169.20°. The dipole moment is 1.779 D along the c-axis.
