Abstract:

 The kinetic processes of the photoionization and dissociation of 4H-furan have been investigated by using synchrontron radiation. The IP of 4H-furan and APs of other ions are gotten from the spectra, the possible channels of dissociative photoionization have been annalyzed. A serices of stable clusters composed of (THF)n. (H2O)n-2H+ (n=2,3,4,5) are present in the MS and the possible structures of the clusters are given.

Key words: 4H-furan, Synchrontron radiation photoionization, Appearance potential, Dissociation channels, Molecular cluster
