Instantaneous dipole moment

[Marni Kahn 1A]

How long does an instantaneous dipole moment typically last?

In my searching I haven't found much more than a description of the duration as "an instant". Probably an arbitrarily brief moment of time that does not bear relevance for topics covered in this class.

Can someone clarify what "instantaneous dipole moment" means/refers to?

[Ally Huang- 1F]

Instantaneous dipoles last for only an instant. Electrons are constantly moving and electron distributions are constantly changing. Therefore, the instantaneous dipoles created by the uneven electron distributions are constantly changing as well.

[Alexandra Bartolome 2H]

I don't think there's a specific length of time; it's simply an instant since there's always fluctuations with electron distribution.

[Shivam Rana 1D]

Instantaneous dipole moments, like Van der Waals forces, last for fractions of seconds in the sense that the electron densities continually shift causing continual and sporadic interactions in different regions of the two molecules.
