We investigate the structure of the neutron rich nucleus $^{14}$B through studies of its breakup in the Coulomb field of a heavy target. The breakup amplitude is calculated within an adiabatic as well as finite range DWBA theories of breakup reactions. Both these formalisms allow the use of realistic wave functions for the relative motion between the fragments in the ground state of the projectile. The longitudinal momentum distributions of $^{13}$B (ground state) following the breakup of $^{14}$B on a heavy target at beam energy of 60 MeV/nucleon, calculated using two possible ground state configurations of $^{14}$B, have been compared with the recent data. The data seem to favour $^{13}$B(${3\over 2}^-)\otimes2s_{1/2}$ as the possible ground state configuration of $^{14}$B with a spectroscopic factor close to unity. We give our predictions for the neutron angular distributions and the relative energy spectra in the one-neutron removal reaction of $^{14}$B.
