In order to study the effect of photoelectron kinetic energy on rotational photoionization propensity rules, rotationally resolved laser photoelectron spectra were measured for excitation of specific rovibronic levels in the {ital D} {sup 2}{Sigma}{sup +} (3{ital p}{sigma}) Rydberg state of NO and their subsequent ionization by radiation at several wavelengths. The measured and calculated ion rotational branching ratios both show a significant dependence on photoelectron energy. Comparison between experimental data and theoretical calculations suggests that a strong {Delta}{ital N}=0 peak in the spectra is caused by an interaction between particular vibronic levels of the {ital A} {sup 2}{Sigma}{sup +} ({ital v}=4) and {ital D} {sup 2}{Sigma}{sup +} ({ital v}=0) Rydberg states.
