1D 1HNMR spectrum (600 MHz) of a 0.025 M solution of 2 in 90% H2O/D2O at 2°C. This spectrum shows that there are two sets of resonances for the imino and methyl protons with a population ratio of 3:1. This ratio is insensitive to temperature (242°C) and concentration (0.0010.025 M) (data not shown). The proton assignments are as follows: d (ppm), 9.17 (CH, s, 1H ´ 75%), 9.14 (CH, s, 1H ´ 25%), 8.61 (AH, q, 3J = 4.8 Hz, 1H ´ 25%), 8.45 (BH, s, 2H ´ 75%), 8.42 (BH, s, 2H ´ 25%), 7.72 (AH, q, 3J = 4.8 Hz, 1H ´ 75%), 6.93 (C31H, d, 3J = 8.4 Hz, 1H), 6.85 (C28H, s, 4J = 2.4 Hz, 1H), 6.82 (C32H, dd, 3J = 8.4 Hz, 4J = 2.4 Hz, 1H), 4.12 (C6H, br, t, 2H), 3.903.83 (C7H, C33H, C40H, m, 6H), 3.733.64 (C34HC39H, m, 16H), 2.98 (C9H, d, 3J = 4.8 Hz, 3H ´ 25%), 2.94 (C9H, d, 3J = 4.8 Hz, 3H ´ 75%). C7NH was suppressed with the solvent peak.
