The early events in halorhodopsin after light excitation are studied with picosecond time resolution. Absorption and fluorescence measurements show that the electronically excited state of the incorporated retinal has a lifetime of 5 ps. Within that time a red-shifted photoproduct is formed that remains stable for at least 2 ns.
利用皮秒时间分辨率研究了光激发后嗜盐菌视紫红质中的早期事件。吸收和荧光测量表明,掺入的视黄醛的电子激发态寿命为5皮秒。在这段时间内形成了一个红移光产物,该光产物至少稳定2纳秒。
