Photoionization Spectroscopy of the Zinc Monoethyl Radical and its Cation
نویسندگان
چکیده
The spectra of the ZnC2H5 radical and its cation have been recorded by two photoionization techniques, respectively resonantly enhanced multiphoton ionization and zero electron kinetic energy spectroscopy. The ionization potential of the radical has been determined along with a number of vibrational frequencies in the ground state of the cation and the excited state of the neutral. Based upon the spectroscopic data, models for the metalcarbon bonding in metal alkyl radicals are proposed that predict relative bond stregths for a number of species.

متن کاملIsomer-selective infrared spectroscopy of the cationic trimethylamine dimer to reveal its charge sharing and enhanced acidity of the methyl groups.
Infrared predissociation spectroscopy of the trimethylamine dimer cation generated by the vacuum-ultraviolet photoionization is isomer-selectively carried out by monitoring two main fragment channels, protonated trimethylamine and the trimethylamine monomer cation. The spectral carriers monitored by these two channels are assigned to different isomers of the trimethylamine dimer cation. One is ...
