The principal components of the hyperfine tensor , due to a n radical coupled to a
proton , can approximately be expressed as ... a and A33 = - ( 1 + a ) a , where a
accounts for the anisotropy and a is the isotropic part of the hyperfine coupling .

In the following we will discuss the hyperfine coupling of the surrounding protons
to the quintet state . We restrict ourselves to the quintet state with Aeso = 4 . 5 cm
- which is encircled in Fig . 5 . 41 ( left ) . In a large magnetic field B , the quintet ...
