Dipole moment of water

  1. Oct 4, 2009 #1
    I understand a little about dipole moment. Its like a compass which aligns itself when an external field is applied.
    But a little fuzzy when it comes to dipole moment of water. why is it 105 degrees. How does this come into play when they are impinged with microwaves or time varying E field.

    The bond angle of water is 105 degrees. The dipole moment is 1.85 debye, so I'm not sure what you're asking.

    Depending on the temperature and hence, the vibrational state of water, its dipole moment will change somewhat.

    How does the bond angle affect the dipole moment. How does it align compared to a regular dipole.
