The well-established physical theory of detonation specifies
the properties of the infinite plane detonation wave in terms of
the thermochemistry of the detonation reaction and the equation
of state of the detonation products, (see, for example, Taylor,
1952). Thus physical chemistry has two roles in the discussion
of the plane detonation wave, the provision of thermochemical
information and the determination of the equation of state.
This theory deals however with an ideal case, in which rate
processes have no effect; in the real wave, complicated rate
processes have to be taken into account. Here again physical
chemistry has information to supply in the fields of chemical
kinetics and rates of energy transfer. The present thesis deals
with contributions to physical chemistry in the fields of thermochemistry, equation of state and intermolecular forces, chemical
kinetics and energy transfer.LIST OF PAPERS:
