RuO$_2$, one of the most widely studied transition metal oxides, was recently predicted to host a novel form of collinear magnetic order referred to as altermagnetism. In this study we combine experiment (reflectance, transmittance, ellipsometry and Raman measurements) and first-principles calculations to elucidate the potential role of altermagnetic order, strain and doping on the optical and vibrational properties of RuO$_2$ grown on TiO$_2$ (001), (101) and (110) substrates. The combination of experiment and theory in this study surprisingly indicates RuO$_2$ is in fact best described if one assumes the nonmagnetic state. Calculations of the altermagnetic state leads to poor agreement with the measured optical and vibrational properties of RuO$_2$.
