The dipole moment of two equal but opposite charges (q +, q −) is defined as the product of charges and the distance separating them; thus it is a vector quantity where the magnitude of the dipole moment vector is q r and the direction is from the negative charge to the positive. 29 0 obj (Relative Permitivity and Refractive Index) x��ZK��6�ϯ�m����#@�81��יC����C��5��~���S|H-�՞�Fb�DQdU�c�G�(�m2�=�����7?q��6$���FZ�L)����:{�?�YQ��oݫ�y�um�+n�����¶��1�?k�W�{u��W�?YD&�G�vU@�zk㗧���}�.��/������˟/~��x}A�V��hA���]�x��5|�9È�� -w Π��~���N�=�8�Q�����@�F��1d��@�I�+�쇚Λd�(��(W��� �X��a�+��a|g CZ _��� .�",H&�F�\|=g�3�Ռg�ͮ=s�DF2BPo�3�I)���'{�yw��X������6.̤ it has magnitude as well as direction.

With the lone pair on the most electronegative atom in both cases we would then expect similar dipole moments (the charge on our deprotonated pyrrole would exist independently of the dipole moment). endobj endobj endobj (Relative Permittivity, Polarization, and Polarizability) It is 1.5 for chloroform and 4.1 for dimethyl sulfoxide. Individual bond dipole moments are indicated in red. In this case, the dipole moment calculated as (via Equation 2 ): μ = Qr = (1.60 × 10 − 19C)(1.00 × 10 − 10m) = 1.60 × 10 − 29C ⋅ m. The Debye characterizes size of dipole moment. This occurs whenever there is a separation of positive and negative charges due to the unequal attraction that the two atoms have for the bonded electrons. (Experiment) The molecular dipole moment can be represented as the sum of the individual atomic dipole moments and the pairwise atomic dipole contributions. << /S /GoTo /D (section.3) >> endobj 1) = q~r (1) where ~r. endobj 1and ~r.
