According to Miguel:

You may apply the 'set' Rasmol command to a 'line' object:
set line color <colour>
set line weight <value>
set line type [ arrow | plain ]
set line x1 y1 z1 x2 y2 z2
The last one sets the line position in the space and draws it.
The arrow point, if line type arrow selected, is to be drawn at the
x2,y2,z2 point.
Or adapt the current gnuplot syntaxt
(to draw an arrow) set arrow from x1,y1,z1 to x2,y2,z2
(to draw a plain line) set arrow from x1,y1,z1 to x2,y2,z2 nohead
set arrow {<tag>} {from <position>} {to <position>} {{no}head}
{ {linestyle | ls <line_style>}
| {linetype | lt <line_type>}
{linewidth | lw <line_width} }

Better take a look to the under development page at
http://bioportal.weizmann.ac.il/dipol-bin/dipol2j.cgi?pdb_id=2ace
I would rather draw the Dipole and Mass moments vectors with arrows.
