The (010), (020), (030), and (001) bands of the 3p ² Rydberg state of the formyl radical have been observed by resonant (1+1) photon ionization spectroscopy from the ²A^' vibronic ground state. Subbands have been re-assigned considering the D_{\infty h} symmetry of HCO in the 3p-state. Renner-Teller effect and Fermi resonances have been analyzed for different subbands.
