Webb22 maj 2024 · The key difference between singlet and triplet state is that singlet state shows only one spectral line whereas triplet state shows the threefold splitting of spectral lines. Moreover, a further difference between singlet and triplet state is that the spin quantum number of a singlet state is s=0 while it is s=1 for a triplet state.
