| Abstract: | The spin-lattice relaxation time (T
1) of
23
Na was measured in solutions of NaClO
4
and (or) NaBr in formamide,N-methylformamide,N,N-dimethylformamide (DMF), MeCN, Me2CO, tetrahydrofuran (THF), and dimethyl sulfoxide (DMSO), and
133
Cs in a solution of CsCl in formamide. The values of (1/T
1)
0
obtained by extrapolation are discussed in terms of current theories of quadrupolar magnetic relaxation of ionic nuclei. A correlation was found between (1/T
1)
0
for
23
Na and Gutmann's donor numbers.For Part I, see ref. 1. |
