通过使用纳秒时间分辨率简并四波混合研究了聚-4-BCMU 聚二乙炔的构象变化。偏振数据以及信号的时间响应表明该信号来自热光栅。简并四波混合信号在杆到线圈的转变过程中发生巨大变化，符合单链构象转变的理论模型。
The conformational change in the poly‐4‐BCMU polydiacetylene was investigated by using nanosecond time‐resolution degenerate four wave mixing. Polarization data along with the time response of the signal indicated the signal to be from a thermal grating. The degenerate four wave mixing signal changes dramatically during the rod‐to‐coil transition and fits a theoretical model of single chain conformational transition.
