|---|---|---|---|---|---|

| w/o Mn2+ | 0.5% Mn2+ | w/o Mn2+ | 0.5% Mn2+ | ||
| 2,2′ | 23.9 | 26.8 | 25.9 | 29.2 | 26.4(1.9) |
| 3,3′ | 30.9 | 31.9 | 31.9 | 31.5 | 31.6(0.4) |

The Δνinhom = Δνexp – (R2/π) i.e. the difference between the experimental full-width at half-maximum linewidth and the experimental relaxation contribution to the linewidth. The average is for the four samples with the standard deviation in parentheses.
