Role of the glassy dynamics and thermal mixing in the dynamic nuclear polarization and relaxation mechanisms of pyruvic acid

Marta Filibian, Sonia Colombo Serra, Marco Moscardini +3

The temperature dependence of ${}^1$H and ${}^{13}$C nuclear spin-lattice relaxation rate $1/T_1$ has been studied in the 1.6 K - 4.2 K temperature range in pure pyruvic acid and in py…
