Dear Seth,

In VMD, press the "2" key (on main keyboard) to activate bond measure
mode; then select the two atoms you want to measure between. The same
applies with angles; key "3" and dihedrals; key "4".

If one is looking at a trajectory and has xmgrace installed, one can
examine the time evolution of such a defined variable above using:

Graphics-->Labels-->Bonds, select bond/angle/torsion defined and then
hit "graph".
