11. The experiments were carried out with a four-sector ZAB-2F-HF/AMD604 mass spectrometer (ref. 5). Methoxy cations were generated by charge reversal (CR) of the corresponding anions [ref. 2(d)]. Hydroxymethyl cations were formed by electron ionization of labelled ethanols. The ions' connectivities were checked by collisional activation (CA) and CR/CA experiments [refs. 2(e), 3(b)]. The metastable ion decomposition products were monitored in MI and CR/MI experiments by scanning the fourth sector.
