This is a trial to simplize sequences to get the relaxation function f 31 (t), which is usually detected by the double-or triple-quantum filtered (DQF or TQF) NMR in an isotropic phase. The results indicate that only two phase cycling is needed to get the f 31 (t) function, which shows the advantage

## Abstract The feasibility of solidβstate magic angle spinning (MAS) ^31^P nuclear magnetic resonance (NMR) spectroscopy and ^23^Na NMR spectroscopy to investigate both phosphates and Na^+^ ions distribution in semiβhard cheeses in a nonβdestructive way was studied. Two semiβhard cheeses of known
Sodium in most biological systems relaxes biexponentially and nentially with fast (R in 2 f and R ex 2 f ) and slow (R in 2s and R ex 2s ) generates a multiple-quantum signal. In a multiple-quantum filtransverse relaxation rates, respectively (4-7). Thus, both tering sequence, the sodium contributin
