Rotationally resolved autoionization spectra of the HCO radical in high-Rydberg states (n = 12 - 50) built on core vibrational states, (010), (020), (030), and (001) have been obtained from rovibrational selected levels of the 3p\, 2 Rydberg state. Autoionization dynamics for bending and stretching modes are analyzed and compared.
