摘要:

手性丙氨酸单晶的极性N⁺H…O氢键在~270 K的自发对称性破缺, 可用变温拉曼振动光谱在b(cc)b几何条件下在线测定. 由于其对手性的灵敏度, 可以测定D-和L-丙氨酸的N⁺H…O氢键在电子自旋翻转相变时的微小能差. 晶体定向能量的正/负, 在于电子自旋的上/下转向, 取决于原子内在磁场的方向. 变温拉曼振动光谱可以观察到: 在D-和L-丙氨酸单晶之间, 拉曼散射光子的波数位移方向相反, 散射光子的不对称度约为1/3. 由于自旋是轴矢量, 样品必须是单晶, 沿轴向测定. 多晶粉末不能观察到相变. 与次甲基(C_α－H)在260 K的自旋翻转相变, 用变温拉曼振动光谱在c(aa)c 几何条件下的相对测量结果接近一致. 本实验提供了一条证明真实手性和“宇称-时间(PT)不对称”的新线索.

Abstract:

Spontaneous symmetry breaking of the N⁺H…O bond in chiral alanine crystals around 270 K was detected in situ by Raman vibrational scattering with b(cc)b geometry. An electron spin-flip transition of the N⁺H…O mode in D-/L-alanine was observed by the scattering of light with left/right orientation and its spin projection antiparallel to the direction of propagation. It is an internal magnetic field originated from the spin-orbit interaction. An obvious Raman wavenumber shift with opposite in sign and roughly one third of the asymmetry (A) of the scattered photon between D- and L-alanine crystals was observed. This shift was not seen in polycrystalline powder measurements because spin is an axial vector. An electron spin-flip transition of the methyne (C_α－H) mode around 260 K was shown to be approximative coincidence by examining the temperature-dependent relative intensity of asymmetric Raman scattering with c(aa)c geometry. This article provides evidence for the true chirality and parity-time (PT) asymmetry in molecular clusters of D- and L-alanine crystals.
