    To experimentally obtain the EPR spectrum described in this video you first tune the magnetic field to find the g-factor for the direction the magnetic field is in with relation to the material. You should then change the orientation of the material with relation to the magnetic field (the x-axis gives this, the angle between the two) to find the principle axis component of g. Once this is done you do the same for the two other ortogonal directions, so you turn the sample around another axis to research the principle values of the g-tensor in other directions. Once you did this in three directions you have three principle components for three orthogonal orientations, which makes the required 3 by 3 matrix of the g-tensor.
