The heats of formation of some simple oxygenated organic compounds were measured from different sources Delta H sub f CH2OH cation 174 kcalmole and Delta H sub f CH3O cation 202 kcalmole. Similar differences exist for the isomers of mass 45. The proton affinities of formic, acetic, and propionic acids were determined from rearrangement ions of esters as about 170-180 kcalmole. The protonated acid ions are readily formed by ionic reactions in the gaseous aliphatic acids. Appearance potential data for H3O ion and CH3OH2 cation may be interpreted to give PH2O approximately P CH3OH approximately 170 kcalmole. Author
