Dissociation of Formic Acid and Deuteroformic Acids by Ion‐Molecule Collision
摘要:
The dissociation of 5.1 kev HCOOH+, DCOOH+, and HCOOD+ ions by ion-molecule collision with H2, D2, He, N2, A, and Kr has been investigated in a mass spectrometer. Approximate values for the cross sections for the resultant fragment ions have been calculated. Positive ion fragments CHO+ and CHO2+. are produced by loss of hydrogen from both of the possible positions. However, rupture of the C–H bond is a factor of two more probable than cleavage of the O–H bond in the formation of CHO2+. The CHO+ ion fragment is formed mainly by removal of the hydroxyl group.
