  CS$_2$ molecules are spatially aligned upon irradiation by intense (1-100 TW
cm$^{-2}$), 35 ps pulses of 512 nm or 355 nm light. When both colours are
simultaneously present, spatial alignment disappears. We draw analogy with
weak-field illumination of an atom by two colours wherein EIT
(electromagnetically induced transparency) inhibits absorption by virtue of
dipoles not being induced in two-colour fields. In the strong field scenario,
molecular alignment is a consequence of a dipole being induced in the direction
of the applied electric field. It follows, therefore, that when dipoles are not
induced, no spatial alignment is to be expected.
