The control theory of nonadiabatically coupled pi-electron rotation (ring current) and molecular vibration in aromatic molecules irradiated by ultrashort laser pulses has been established. Theoretical and numerical analyses have revealed that it is possible to manipulate the interference between nuclear wave packets created on excited-state potential energy surfaces by a laser pulse of arbitrary polarization. In principle, the angular momentum (magnetic field) of pi electrons circulating along an aromatic ring and the amplitude of molecular vibration can be controlled as desired by means of ultrashort laser pulses. In addition, the frequency spectrum of photo-excited aromatic molecules depends significantly on laser polarization. This finding serves as a basis for rapid identification of molecular chirality.

建立了超短激光脉冲作用下芳香族分子π电子转动（环电流）和分子振动的非线性耦合控制理论。理论和数值分析表明，它是可能的操纵由任意偏振的激光脉冲在激发态势能面上产生的核波包之间的干涉。原则上，通过超短激光脉冲，可以根据需要控制沿着芳香环循环的π电子的角动量（磁场）和分子振动的振幅。此外，光激发的芳香族分子的频谱显着依赖于激光偏振。这一发现为快速鉴定分子手性奠定了基础。
