  The properties of T=0 neutron-proton correlations are discussed within the
frame work of different model calculations. Single-j shell calculations reveal
that the T=0 correlations remain up to the highest frequencies. They are more
complex and cannot be restricted to L=0 pairs only. Whereas it may be difficult
to find clear evidence for T=0 pairing at low spins, T=0 correlations are found
to induce a new excitation scheme at high angular momenta.
