- quinacrine band(Q band) Q帶, 芥子喹吖因帶
- The results showed that, the UV/Vis spectra were merely influenced by the concentration of solutions of different solvents for about only 1~2nm shift of Q band. 通過(guò)細致分析,發(fā)現在不同溶劑中,酞菁濃度對電子吸收光譜的影響較小,范圍只有1~2nm 左右。
- There is a red shift for the excimer in the fluorescence emission spectrum and a blue shift for the aggregation form in the electronic absorption spectrum of the Q band. 在熒光光譜中金屬萘酞菁的激基合物熒光峰相于單體熒光峰發(fā)生紅移,在吸收光譜中金屬萘酞菁基態(tài)聚集體的收峰相對于單體吸收峰發(fā)生藍移,聚集體的熒光光譜和吸收光譜有鏡像對稱(chēng)關(guān)系。
- In the UV-vis of the subtitutional phthalocyaninatometal axis complex, the Q band of phthalocyaninatometal axis complex is einstein shift more than 4 nm comparing with the phthalocyaninatometal. 由于苯氧基的引入,共軛體系增加,使酞菁Q帶表現出一定程度的紅移,而B(niǎo)帶明顯變寬。 而在軸向配合物的紫外-可見(jiàn)光譜圖中我們可以看到,生成配合物的Q吸收帶比未生成配合物酞菁的Q吸收帶紅移了4個(gè)多納米,且吸收峰明顯變窄。
- It can be seen from the UV-vis of the subtitutional phthalocyaninatometal that the Q band of phthalocyaninatometal is einstein shift with the subtitutional group and B band of phthalocyaninatometal broadens greatly . 結果顯示,各個(gè)金屬取代酞菁分別有與它們分子量相吻合的分子離子峰。 在各個(gè)酞菁的紫外-可見(jiàn):光譜圖中能看到明顯的兩個(gè)酞菁特征吸收帶:Q帶和B帶。
