Original BASIC program by John Sheridan
Modified by Robert McMahon and later converted to Javascript by Paul Bonvallet
This program determines the zero-field splitting parameters
|D/hc| and |E/hc| of a triplet carbene by applying a least-squares fit
of the observed ESR transitions to a set of equations outlined
in the literature.
