1.MNDO calculations and group theory were carried out on tetraphenyl porphyrine(TPP) to obtain its optimum molecular geometry.
运用MNDO计算和群论,优化得到了较满意的中位取代苯基卟啉(H2TPP)的分子构型。
2.An investigation is also made on determining DMDAAC qualitatively by bromophenol blue test and quantitatively by tetraphenyl boron sodium precipitation reac...
