We propse a method that uses a static magnetic field to enalbe direct optical excitation of forbidden electric dipole transitions that are otherwise prohibitively weak. The method is based on mxing of atomic states by a static magnetic field. The methid can also be viewed as a limiting case of two-photon spectroscopy, where the frequency of one of the fields--a magnetic field, in this case -- is equal to zero. Using this method, we calculate that an optical lattice-based ytterbium standard could achieve a fractional frequency uncertainty of less than 10-17 for the metrologically preferred even isotope.
