Schematic geometrical representation of the three compounds under consideration.

FIG. 2.

The three dominant negative ion yields from furan (FN). In the energy range below only a small signal due to the furanyl anion is detected (see insert at different intensity scales).

FIG. 3.

Negative ion yields from tetrahydrofuran (THF). The weak signal at is due to a metastable parent anion (see the text).

Image of FIG. 4.
FIG. 4.

Fragment anions arising from fructose by the abstraction of one, two, and three neutral water molecules, respectively. Scans on an extended energy scale (up to ) did not result in detectable signals at these mass units.

FIG. 5.

Mass numbers of fragment ions from fructose arising from complex DEA reactions. For the assignment of the DEA reactions, see the text. Scans on an extended energy scale (up to ) did not result in detectable signals at these mass units.

Fragment ions from fructose appearing at higher energies. and can be formed via a single bond rupture while is expelled from the C–O–H group. The spectrum contains the background signal which is also present in the UHV apparatus, when the sample is switched off (see the text).
