7.~1H chemical shifts of H_a in D_2O increase with the increasing bulk of N~1-substituent of MI, IE, IP and IMP.
在D_2O中，H_a的化学位移随着N~1-取代基体积增大而增加； 而在CDCl_3中，其结果是它的化学位移的数值随N~1-取代基体积增大而减少。收藏指正
8.~1H chemical shifts of H_a in CDCl_3 decrease with the increasing bulk of N~1-substituent of MI, IE, IP, IMP and IPP.
H_b也有类似的规律。 H_a和H_b在两种溶剂中的~1H化学位移的变化值(Δδ(D_2O-CDCl_3)_(exp))随着咪唑环上的N~1-取代基体积增大而增加。收藏指正
9.Synthesis and Biological Activity of Methyl N-Methoxy-N-[2-(1,6-dihy- dro-1-substituent-6-oxo-pyridazin-3-yloxymethyl)phenl]carbamates
N-甲氧基-N-[2-(1,6-2H-1-取代-6-羰基-哒嗪-3-氧甲基)苯基]氨基甲酸甲酯的合成及生物活性研究收藏指正
10.Under the same conditions, l-naphdiylamine-7-sulfonate and l-naphthyiamine-8-sulfonate can not emit RTF signal. The results show that the position of substituent has important effect on RTP emitting.
检出限分别为3.8×10~(-9_、1.4×10~(-7)和2.8×10~(-8) mol/L。1-氨基 7-萘磺酸盐和1-氨基 8-萘磺酸盐在相同条件下则不能产生RIP信号,表明取代基位置对RTP发射有重要影响。收藏指正
