Eq. 4 with N = 2 was applied to the and the data for both water and formate protons. The constant A′ represents the residual relaxation rate constant remaining at the high field end for all of the fits tabulated here. The data for of the formate proton was fit in a similar fashion except with N = 1. Eq. 3 with N = 2 and physical constants corresponding to an electron was applied to the and the data for the formate protons and to the data for the acetate protons. The units of the correlation times are in seconds (s) and for the relaxation rates are s−1. Errors for the fitted parameters are estimated at 20%.
