In their MS breakdown mechanism, coordination of pyridyl moiety to iron atom is proposed.

在該類(lèi)化合物的質(zhì)譜裂解中，發(fā)現(xiàn)吡啶環(huán)對(duì)鐵原子存在配位作用95视频在线免费观看。

The maximal absorption band could be assigned mainly to intra-ligand charge transfer transition character. It mostly originated from transitions starting from the phenoxide side containing chlorine to pyridyl side.

最大吸收主要來(lái)自配體內(nèi)電荷轉(zhuǎn)移躍遷一二三四日本高清视频动漫，電荷從苯酚環(huán)和氯向含氮的吡啶環(huán)躍遷。

The results suggest that the electronic π-π* transitions in AlQ_3 are localized on the quinolate ligands; the transition from a phenoxide donor to a pyridyl acceptor includes C→C and O→N transferences. There hardly is any relation to the metal aluminum.

結(jié)果表明国产原创自拍视频在线观看网，電子從基態(tài)躍遷到低激發(fā)態(tài)時(shí)主要為π-π*躍遷曰韩性爱无码无毛片儿；電荷從含氧的苯酚環(huán)轉(zhuǎn)移至含氮的吡啶環(huán)上，包括兩環(huán)之間 C→ C轉(zhuǎn)移和 O→ N轉(zhuǎn)移欧美专区福利，與金屬離子關(guān)系不大人人射色综合网。

A series of N -bonded donor-acceptor derivatives of phenothiazine containing phenyl, anisyl, pyridyl, naphthyl, acetylphenyl, and cyanophenyl as an electron acceptor have been synthesized.

合成了一系列的N10位取代的吩噻嗪給體受體衍生物，這些受體基團(tuán)包括苯日本乱人伦视频一区二区三区，苯甲醚国产区精品尤物柚木在线，吡啶，萘精品免费观看69影院，苯乙酮和苯甲腈r日韩一级黄色网站。

In the complex, the tin atom is hepta-coordinated in a distorted pentagonal bipyramid including a bridging pyridyl N atom, by which the one-dimensional infinite chain is formed.

結(jié)果表明，該化合物中錫原子配位數(shù)為7www.国产.com，處在畸變五角雙錐配位場(chǎng)中久久人人插，化合物通過(guò)吡啶基氮原子的橋連作用形成了一維無(wú)限鏈狀結(jié)構(gòu)。
