Abstract

Vibrational predissociation spectroscopy of the HOOC(CH2) 10COO- and -OOC(CH2) 10COO- anions is carried out by predissociation of weakly bound H2 molecules. The HOOC(CH2)10COO - (H2)2 and -OOC(CH 2)10COO- (H2)10 cluster ions are formed by H2 attachment to the electrospray-generated bare ions in an ion trap cooled to below 20 K using a closed cycle helium cryostat. The photofragmentation behavior indicates that the H2 binding energy is about 600 cm-1, which is similar in strength to that found in Ar-tagged ions. The spectra indicate that the monoanion adopts a cyclic structure through the formation of an asymmetrical, internal anionic H-bond.
