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 3ppi\, 2Pi Rydberg state. Autoionization dynamics for bending and stretching modes are analyzed and compared.
