Hi,
  No, it is not possible. OpenGL requires a front and rear clipping
plane at a hardware level, and they cannot be disabled, only set to
nearly zero (near) and nearly infinity (far).
If you want to get "closer" you can instead translate the molecule
farther away and then scale it up, and you can also change the combination
of display height/distance options to make the rendering look the
way you want. Let us know if you need more help with this.

Cheers,
  John
