13C Relaxation Data 
Relaxation dispersion CPMG-based experiments have been proposed to measure slow time-scale dynamics of side chains methyl groups ( 01JACS4556 and 02JACS1443 ) and carbonyl carbons ( 04JB187-29 ) in proteins.

Application of 13C T2 measurements: ( 99JACS2891 , 92BIO5253 , 99JACS2891 , 93JACS6333 , 99JACS11589 )
