对20多种β双酮、吡唑酮及酚(包括苯酚)型的黄、品、青成色剂分子作了~1HNMR谱的测定和解析。并用INDOR技术和自旋模拟程序等确定了~1H化学位移和偶合常数。还对分子内的受阻旋转、活泼氢状态以及互变异构体的动力学现象作了讨论。
1H NMR spectra of more than 20 kinds of β-diketone, pyrazolone and phenol (including phenol) -type yellow, green and blue coupler molecules were determined and analyzed. The ~ 1H chemical shifts and coupling constants were also determined using INDOR techniques and spin-simulation programs. The intramolecular hindered rotation, the state of active hydrogen, and the kinetics of tautomers are also discussed.
