Summary
The textbook by Forst [73.F] provides a number of interesting exercises which I do not propose to duplicate. Instead, I will suggest below a selection of computational experiments, all of which can be undertaken once the basic algorithms in Appendix 3 have been assembled together in an available machine and the inevitable organisational conflicts have been resolved. I would suggest that, initially, the student should practise with a few computer runs in which only the input parameters are varied, in order to find out the general behaviour of the method; several of these are listed first. Then follow a number of fairly extensive numerical experiments, each marked *, which are designed to illustrate relevant points of the theory; most students will not have the time to venture beyond these. Finally, for the student whose concern is primarily with the unimolecular kinetic problem, there are three marked ** and ***, which are more involved: the first two can be completed either by a small amount of reprogramming of the routines MAIN and UNIRAT, or by the construction of small routines specially designed for the problem, but the last one should not be attempted without a thorough understanding of the procedures used to calculate sums and densities of states.
Any reaction may be chosen as the subject for each calculation, but the methyl isocyanide isomerisation provides a fairly realistic example of a strong collision reaction without consuming too much computer time; data sets are given for both methyl isocyanide and cyclopropane.
