THE MICROWAVE SPECTRA, STRUCTURE AND DIPOLE MO MENT OF "CIS" N2F2

Abstract

The microwave spectrum of one isomer of F14N14NF and F15N14NF is reported and from this the structure is derived as planar and ''cis'' with the following structural parameters: d(NN) 1.214 = 0.005 Angstroms, d(NF) 1.384 = 0.01A < FNN 114.5 = 0.5 degrees. A dipole moment of 0.18 = 0.01D has been evaluated fr rotational Stark effect. Transitions of the molecule in an excited vibrational state are reported. From relative intensity measurements of this state, a vibrational frequency of 300 = 35 reciprocal cm is estimated. A method is demonstrated enabling the ratio of nuclear spin statistical weights of two levels to be determined from the growth rate of their intensity with increasing Stark modula tion voltage.
