J. Alnis et M. Auzinsh, Alignment-orientation conversion in molecules in an external magnetic field caused by a hyperfine structure, EUR PHY J D, 11(1), 2000, pp. 91-97
The paper presents a discussion on the problem of alignment-orientation con
version in an excited state of molecules. It is shows 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 int
eraction. The orientation thus: created is transverse, i.e. perpendicular t
o the direction of the external magnetic field. The magnitude of this effec
t is analyzed as dependent on molecular parameters.
