  The alternative to dynamic alignment explanation of experimental results on
spatial-asymmetric dissociation of molecules in a laser field is proposed. The
concept of geometrical alignment is sufficient for explanation of these
results. In this case the spatial anisotropy of interaction of molecules with
laser radiation is transferred from one field to another through the ordinary
mechanism of nonlinear optical interactions. Thus laser radiation does not
create alignment, but only registers it. A physical basis of such nonlinear
processes is inequality of forward and reversed optical transitions that
corresponds to a concept of time invariance violation in electromagnetic
interactions. Directions of the further researches in the field of alignment
spectroscopy are discussed.
