Examples
- P - nitryl chlorine benzyl formate
硝基氯甲酸苄酯 - O - nitryl chlorine phenyl formate
硝基氯甲酸苯酯 - Polynitropolyphenylene ( pnp ) , as binder , has high heat - resistance , with three nitryl groups at 1 - , 3 - , 5 - position in a phenyl ring . pnp , distinguished by property of low crystallization , which can be compatible with plasticizer , has a formation heat of 164 . 3j / g and high oxygen content
它不容易结晶，易于成膜，能与多种增塑剂相容； pnp的生成热为164 . 3j g ，具有较高的氧含量， pnp能很好的解决火炸药能量和安全性能之间的矛盾。 - We have calculated one - and two - photon absorption cross sections of the lowest excited states of a series of molecules combined with benzene , stilben , thiophene as center attached with amine , diphenylamine , diethylamine as electron - donor and nitryl as electron - acceptor ; the effects of molecular length , n center and electron - donor on two - photon absorption cross sections have been studied and all calculations have been carried out using the density functional theory at an ab initio level . it is found that the molecular length and the one - photon absorption intensity are quite strongly c orrelated factors , and that a corresponding correlation for the two - photon absorption is decreasing . it is also found that a most crucial role for the two - photon absorption is played by the n center
我们分别以苯、二苯乙烯、噻吩为中心，氨基、二苯氨基和二乙氨基为电子给体，硝基为电子受体组合形成的分子为研究对象，在从头计算的水平上用密度泛函理论计算了这些分子在低激发态下的单、双光子吸收强度，重点研究了分子的长度、中心和给体的供电子能力对分子单、双光子吸收的影响。研究结果表明，分子长度与单光子吸收强度之间有密切关系，而在双光子吸收中这种关系较弱；中心在双光子吸收中具有重要的作用；在中心和受体一定的情况下，增加给体的供电子能力，可提高双光子吸收强度。
