Combining heavy quark effective theory and the chiral Lagrangian approach we investigate radiative decays of pseudoscalar $D$ mesons. We first reanalyse $D^{*} \rightarrow D \gamma$ decays within the effective Lagrangian approach using heavy quark spin symmetry, chiral symmetry Lagrangian, but including also the light vector mesons. We then investigate $D \rightarrow V \gamma$ decays and calculate the $D^0 \rightarrow \bar{K}^{*0} \gamma$ and $D^{s+} \rightarrow \rho^+ \gamma$ partial widths and branching ratios.

Combining heavy quark effective theory and the chiral Lagrangian approach we investigate radiative decays of pseudoscalar $D$ mesons. We first reanalyse $D^{*} \rightarrow D \gamma$ decays within the effective Lagrangian approach using heavy quark spin symmetry, chiral symmetry Lagrangian, but including also the light vector mesons. We then investigate $D \rightarrow V \gamma$ decays and calculate the $D^0 \rightarrow \bar{K}^{*0} \gamma$ and $D^{s+} \rightarrow \rho^+ \gamma$ partial widths and branching ratios.

We present the expected range of the branching ratios for these decays, the most frequent ones $D^0\to \bar{K}^{*0}\gamma$ and $D^+_s \to \rho^+\gamma$, being a few times $10^{-4}$.

We follow the approach of Fajfer et al., who studied radiative two-body decays $D→V γ$ [ref] and Cabibbo allowed three-body decays $D→K^- π^+ γ$ [ref] and $D →K^0 π^0 γ$ [ref] in this way.
