Kinetic Energy Distributions

A general procedure is presented for determining the distribution of translational energies released in unimolecular ionic reactions occurring in the analyser of a mass spectrometer. It is shown that the method is applicable to reactions in which the average kinetic energy release covers a wide range (< 1 meV to ca . 3 eV). The treatment avoids making approximations either in the calculation of metastable peak shapes or in the subsequent determination of the translational energy distribution. Excellent agreement is achieved between experimental and calculated metastable peak shapes and the kinetic energy distributions represent the first accurate values obtained by a generally applicable technique. The relation between the average kinetic energy released and the width at half height of the corresponding metastable peak has been explored for peaks of various shapes. For gaussian-type peaks the kinetic energy release calculated from the half height is smaller by a factor of two to three than the average value, while for dish topped peaks it approximately equals the average value.

Quantum Simulations

We present an account of our recent effort to improve simulation of the photodissociation of small heteroaromatic molecules using the Ab Initio Multiple Cloning (AIMC) algorithm. The ultimate goal is to create a quantitative and converged technique for fully quantum simulations which treats both electrons and nuclei on a fully quantum level. We calculate and analyse the total kinetic energy release (TKER) spectra and Velocity Map Images (VMI), and compare the results directly with experimental measurements. In this work, we perform new extensive calculations using an improved AIMC algorithm that now takes into account the tunnelling of hydrogen atoms. This can play an extremely important role in photodissociation dynamics.
