“…6) and a critical energy for CH,OCH-CHt'-C,H,O+ of 10.56 eV." This value is higher than would be predicted by values in Table 2, as the fragmentation has a reverse critical energy.…”

“…Simple dissociation typically quickly suppresses alkane eliminations with increasing internal energy. 10,11,14,33 It also implies that complex-mediated H-transfer becomes much faster than intramolecular rearrangement at energies further above threshold than those accessed in the alkane eliminations. This suggests that at those energies there is relatively little relative movement of the partners prior to H-transfer.…”

“…The adiabatic ionization energy could be lower by 0.05 eV owing to low ion count and structure in the curve near threshold. A range of predicted values is given for m/z 70 because, as from ionized n-butanol, 30 water elimination from 2-pentanol probably gives a mixture of C 5 H 10 Cž products. AE C 5 H 10 Cž , 9.90 eV, is lower than expected for formation of cyclopentane (10.45 eV) or methylcyclobutane (10.31 eV) ions, indicating some formation of a more stable C 5 H 10…”

“…Unimolecular decompositions of ionized isopropyl methyl ether [(CH 3 ) 2 CH‐OCH 3 , MW 74] have been studied extensively 1–10. Many of these studies were addressed to the losses of CH 3 and CH 4 from the molecular ion 3–10. The kinetic energy release (KER) accompanying the loss of CH 4 from the molecular ion was also measured4, 10 to clarify the fragmentation mechanism.…”
