TRAPPED ION PHOTODISSOCIATION SPECTROSCOPY - THE ELECTRONIC-SPECTRUM OF THE HYDROGEN-BONDED COMPLEX CATION [C6H5OH-N(CH3)3]+

The electronic spectrum of the hydrogen-bonded complex cation, [C6H5OH-N(CH3)3]+, has been observed by trapped ion photodissociation spectroscopy, in which the yield spectrum of the product ion H+N(CH3)3 was acquired for the complex ion stored in a cylindrical ion trap cell. The spectrum in the range of 350-430 nm revealed that the stable complex cation has a structure composed of phenoxy radical and protonated trimethylamine, that is, C6H5O-H+N(CH3)3. The dissociation process of the photoionized complex was discussed.
