Describes a Fortran program that illustrates how the end-to-end distances in randomly coiled polymer molecules is affected by varying the number and lengths of chains and the angles between them. (MLH)

Describes a computer program that allows the numerical solution of an acid-base equilibrium polynomial equation without the need for chemical approximations. (MLH)

Discusses a computer program that has been used in environmental chemistry courses as an example of modelling as a vehicle for teaching chemical dynamics, and as a demonstration of some of the factors which affect the production of smog. (Author/GS)

The application of molecular mechanics (a nonquantum mechanical method for solving problems concerning molecular geometries) to calculate force fields for n-butane and cyclohexane is discussed. Implications regarding the stable conformations of the example molecules are also discussed. (Author/SK)
