WebF2, of a pre-reactive complex of oxirane and F2 were observed with a Balle-Flygare microwave spectrometer. Chemical reaction between the components was avoided by use of a fast-mixing nozzle. WebThe high resolution Fourier transform technique has been extensively applied in the centimeter range. In the past few years great progress have been made in observing molecular complexes. Most instruments operate between 2 and 26 GHz. So, very light interesting molecular species cannot be observed.
