Scientific paper

Combining heavy quark effective theory and the chiral Lagrangian approach we investigate D meson radiative decays. First, we reanalyse $D^{*} \rightarrow D \gamma$ decays using heavy quark spin symmetry, chiral symmetry Lagrangian, but including also the light vector mesons. Then, we calculate branching ratios $D \rightarrow V \gamma$. We make some comments on the Cabbibo suppressed decays $D \to \rho / \omega \gamma$ and the branching ratios of $D \rightarrow P P \gamma$ decays.
