WebJan 28, 2024 · In gases however, atoms will be spaced loosely enough such that the interaction between atoms will be minimal. This allows the energy levels to have sufficient difference in energy for distinct lines to be formed. You see line spectra usually only in gases because there the interaction between the atoms can be neglected.
