摘要

基态的矫形器的存在结晶紫(CV)自1942年以来一直在争论当刘易斯提出的,并且和Lipkin.1他们建议两个矫形器在醇解释肩膀的消失(~ 550 nm)和增强峰值(~ 590海里)的吸收光谱在低温(114 K)。主要构象异构体,分配到峰值的起源,是假定D3对称(螺旋桨类型)中所有苯组在相位倾斜。第二个构象应该具有C2对称(扭曲的螺旋桨型),被定位为肩的起源,其中一个苯基在相反的方向倾斜。

Ultrafast population transfer in ground states: evidence for two ground states of crystal violet
The presence of ground state conformers of crystal violet (CV) have been in dispute since 1942 when proposed by Lewis, Magel, and Lipkin.1 They suggested the two conformers in alcohols to explain the disappearance of a shoulder (~550 nm) and the enhancement of a peak (~590 nm) in the absorption spectrum at low temperature (114 K). The predominant conformer, which was assigned to the origin of the peak, was assumed D3 symmetry (propeller type) in which all phenyl groups are tilted in phase. The second conformer was supposed to have C2 symmetry (distorted propeller type), being sited as the origin of the shoulder, in which one of the phenyl groups is tilted in the opposite direction.
