Abstract The Langevin equation governing the time dependent dipole moment μ(t) of an accidental symmetric top (i.e., the direction of μ(t) does not coincide with the axis of symmetry) in an external electric field is directly derived from the Euler-Langevin equation. Results which have been previously obtained in J. Mol. Liquids. 1991, 49, 79 are regained as special cases. The scalar Langevin equation governing the longitudinal component of μ(t) along a space fixed axis is also derived.
