a

β was estimated by simulation of all processes.

b

The average β = 0.67 for nitroxyl in water:glycerol was used for estimation of CA,g.

c

β estimated from the tumbling process (1/T1(water glycerol)-1/T1(glycerol)), as in Figure 9.

d

The value above the glass transition temperature.

e

Clocal and Δlocal for these solute/solvent combinations were estimated from nitroxyls in sucrose octaacetate.

f

WG is water:glycerol

g

Except for the rows identified with (Q), experiments were performed at X-band.

h

CA,g (experimental)/CA,g (theory) including β.
