Parallel orientation lower in energy than antiparallel orientation

  1. Jun 16, 2006 #1
    Why is the parallel orientation slightly lower in energy than the anitiparallel orientiation?

    What is the context of your question?

    Because [itex]-cos(0) < -cos(2\pi)[/itex]

    Slight typo there Gokul, because [itex]-cos(0) < -cos(\pi)[/itex]

    Gah, yes of course.

    However, the point I was trying to convey was that the question needed to be more specific for the answer to be meaningful.

    Don't just say you are sorry- be more specific! What is the context of the question? What is it that is "parallel" or "anti-parallel" and what energy are you talking about?
