Magnetic dipole

  1. Jun 23, 2008 #1
    How can the magnetic dipole of a molecule (Oxygen for example) affect radiation absorption?

    In general I believe fine structure is possible involving rotational spectra (microwave range) even without a permeanent dipole moment in rotating molecules. Molecular rotation corresponds to a magnetic dipole moment which can interact with the spin mag. moment of electrons.

    ex. see:http://en.wikipedia.org/wiki/Rotational_spectroscopy

    Well I started to figure out the main idea

    But can energy excitations using , for example, electron spin resonance induce or increase magnetic dipole moment ? thus shift (increase) the frequency of the absorbed spectrum ?
