Double resonance strong field experiment

Fig. 13. Strong-field blanking experiment (A) and (B) are both frequency-swept mass spectra of C Xg products from the reaction of parent ions in a 1 1 mixture of C3D6 with C3H6. The electron energy was adjusted so that only parent ions were present and the total conversion to product was about 15%. In spectrum (A), no double-resonance field was present. In spectrum (B), the C3D6 ions were irradiated with a strong rf electric field in the ion source, so that they were ejected from the cell before leaving the analyzer.
