Theoretical research has provided compelling arguments that                     magnetic fields play an important and perhaps essential role in                 the formation of stars out of clouds of material in the                         interstellar medium.  Empirical tests of these theoretical                      results are very important.  Possible tests are: (1) the                        measurement and mapping of the strengths of the magnetic fields                 in dense clouds by observations of the Zeeman effect on spectral                lines of neutral atomic hydrogen, hydroxyl, and other molecules;                (2) determination of cloud masses, sizes, kinematics, and                       densities by observation and mapping of millimeter-wave lines of                selected molecules in order to assess the dynamical importance of               magnetic fields; (3) measurement of the variation of the                        fractional ionization of molecular species in clouds in order to                estimate the conditions for freezing the magnetic field flux; and               (4) determination of the mass-to-magnetic flux ratio and its                    variation within a cloud.                                                                                                                                       This grant supports an observational research project conducted                 by Dr. Richard Crutcher, at the University of Illinois, in                      collaboration with Dr. Thomas Troland, at the University of                     Kentucky, to test the current theoretical ideas in all of the                   areas outlined above.
