The vacuum ultraviolet photoionization mass spectrum of CH3OF displays a prominent parent ion peak, whose adiabatic onset is 11.340±0.008 eV, although much lower energy fragmentation processes (CH2O++HF, 8.0 eV; CH2OH++F, 9.3 eV) are possible. These lower energy processes have very low intensity. Two higher energy processes, to CH+3+OF and CH2O++H+F, are observed. Their thresholds are used to determine ΔH0f0 (CH3OF)≥-23.0±0.7 kcal/mol, or D0 (CH3O–F)≤47.4±1.2 kcal/mol. CH2OF+ is a significant fragment, whose appearance energy leads to ΔH0f0 (CH2OF+)≊215.1±0.8 kcal/mol. [ABSTRACT FROM AUTHOR] |
