摘要
太赫兹辐射是指频率范围在0.1×1012~10×1012 Hz之间的电磁辐射, 而生物分子的链、键振动频率大于1014 Hz, 故太赫兹光子难以引起生物分子的共振吸收效应。但按Frohlich的理论, 活的生物分子系统是具有高度相干性的系统, 其运动状态具有内部协同的集体振荡效应, 该集体振动模的频率为0.02×1012~2.0×1012 Hz。因此, 太赫兹光子是能够与活的生物分子系统发生相互作用的,并产生相应的共振吸收效应。在偶极近似条件下, 可通过太赫兹光子与生物分子振子相互作用的哈密顿量, 求解相应的薛定谔方程, 可解释太赫兹光子的荧光效应; 并讨论了太赫兹光子对生物细胞膜的作用效应机制。
Abstract
The frequency range of THz radiation is 0.1×1012~10×1012 Hz, but the frequency of the band of biomolecule greater than 1014 Hz. Hence the interaction of THz photon with the bond of biomolecule can not lead to the resonance effects. However, according to Frohlich theory, living biomolecule system is a extreme coherence's system, its motion state poeeseees the collective vibration effect. The range of coherent vibration frequency is 0.02×1012~2.0×1012 Hz. Hence, the interaction of THz photon with the living biomolecule system can lead to the resonance effect. Under dipole approximation, the Hamiltonian of the interaction of THz photon and biosystem vibrator can take. To solute the Schrdingar equation, we can explain some fluorescence effect that are cause by THz photon’s action. Other, we discussed the mechanism on action effects of the laser photon acting to protein or cell membranes.
