  We evaluate the couplings of pions in the transitions of positive parity
heavy mesons, (1+,2+) and (0+,1+), to negative parity ones (0-,1-) using a
technique which is not limited to the soft-pion limit. This is made through a
constituent quark-meson model (the CQM model) where the amplitudes are obtained
by quark loops with mesons on the external lines. The results are in good
agreement with experimental data.
