Abstract. The paper presents a discussion on the problem of alignment-orientation conversion in an excited
state of molecules. It is shown that a rather strong alignment-orientation conversion effect in the excited
molecular state can be caused by a joint action of an external magnetic field and hyperfine interaction. The
orientation thus created is transverse, i.e. perpendicular to the direction of the external magnetic field.
The magnitude of this effect is analyzed as dependent on molecular parameters.
