Spectra of the NO-Ar complex have been recorded using REMPI spectroscopy in the region corresponding to transitions to the $3p$ Rydberg states in uncomplexed NO. Additionally, spectra have been simulated using $ab initio$ techniques with the aim of better understanding this region, as previous favourable results have been obtained using a similar approach for the $3s$ Rydberg state, \textbf{129}, 244303 (2008)}. Excellent agreement with the REMPI spectra is seen for the $3p\pi$ state simulation. Results on the $3p\sigma$ state will be discussed, along with extension to other NO-Rare Gas complexes.
