In this study we have developed the classical four-body problem using
a system of hyperspherical coordinates proposed by Ohm and Linderberg
[Mol. Phys. 49, 53 (1982)]. Expressions are given for the canonical mo
menta, principal moments of inertia, total angular momentum, kinetic e
nergy, and, finally, the Hamilton equations of motion. (C) 1999 John W
