Would the atomic emission spectra for sodium be the same on Earth as on the moon?

The atomic emission spectra for sodium would be the same on Earth and the Moon, as these spectra are determined by the electronic transitions of sodium atoms, which do not change based on location. However, the observed intensity and clarity of the spectra might differ due to atmospheric effects on Earth, such as air pressure and composition, which do not exist on the Moon. In a vacuum, like that on the Moon, the emission spectra would be more easily observed without interference.
