If you want to make a movie, write a Tcl script that would cross-blend
the two molekules:

1. Create molekules' representations that you like.
Each "molekule" should have its own material: for example, set the
material for the first molecule to "AO Shiny". Then use "Material" menu
to duplicate "AOShiny" and call it something like "AOShiny2" (or however
you want). Assign this duplicate material to the second molekule.

2. Then, you will write a loop something like:

set n 1000
for {set i 0} {$i < $n} {incr i} {
     material change opacity AOShiny [expr {($n-($i+1))*1.0/$n}]
     material change opacity AOShiny2 [expr {($i+1)*1.0/$n}]
     render TachyonLOptiXInternal blend_[format %04d $i].ppm
